Birkat HaMazon D'Rabanan: Rabbinic Source
Although the mitzva d'oraita is to thank God only when you are satiated from the meal, chazal decreed that we say birkat ha'mazon even when eating only the volume of a k'zayit and even if not satiated. So you must still say birkat ha'mazon after eating at least 1.3 fl. oz. (39 ml, or 1/6 cup) of bread within four minutes--even if you are not full.  This is known as birkat ha'mazon d'rabanan.
Jewish Festivals: Medicines: When To Take: D’Rabanan Festival Days
You make take medicines for any reason on d'rabanan Jewish festivals--even medicines not allowed on the first day of Jewish festivals--except:
  • Medicines that you smear on skin.
  • If the Jewish festival falls on Shabbat (which can only be second day of Shavuot).
    Note The d'rabanan Jewish festivals are the second day of Jewish festivals except Rosh Hashana (actually, the second day of Rosh Hashana IS d'rabanan but has the status of d'oraita), plus the last day of Passover and Sukkot outside of Eretz Yisrael.
Asking Non-Jew To Do Melacha D'Rabanan
You may directly instruct or ask a non-Jew to do melacha d'rabanan for you on Shabbat, but only:
  • To prevent a large financial loss.
    Note A large loss is subjective to the individual's actual wealth and also to that person's perception of what is a large loss. Consult a rabbi.
  • For Shabbat needs.
    Example You may ask a non-Jew to unlock an electric hotel door or trigger an entrance door on Shabbat, since this is for a Shabbat need and the action is not prohibited d'oraita.
    Situation A new guest arrives and you need the space on the table occupied by your Shabbat candlesticks.
    What To Do You may not move the candlesticks, but you may ask a non-Jew to do so.
    Situation You left a non-muktza item that you now need for Shabbat on a tree branch (or a child left one in a tree house!).
    What To Do You may not climb the tree to retrieve the item, but you may ask a non-Jew to retrieve it. Example You may ask a non-Jew to turn on air conditioning.
    ExampleYou may ask a non-Jew (directly, no need to hint) to turn off a light if it interferes with someone's sleeping.
    • To allow doing a mitzva.
    • For other pressing (and certainly for life-threatening) needs, such as health, even if the person not sick.
    Note All of these are d'rabanan cases!
Introduction to Jewish Festivals: Selecting/Boreir
Issues of boreir are almost always d'oraita, not d'rabanan, and therefore we are stringent in applying restrictions concerning boreir.
Unlike on Shabbat (when you must remove some good along with the bad so as not to violate the melacha of boreir), on Jewish festivals you may remove the bad from the good if it is easier to take the undesired food from the desired food.

Desired from Undesired
You may select desired food from undesired (or inedible) substances if you follow these two rules:
1. Cannot Use Specialized Separating Utensil
    Don't use a utensil--such as a slotted spoon, peeler, or sieve--that is specialized
    for separating:
  • Food from other food, or
  • Food from other substances.
    Note You may remove dirt from a carrot's surface by scraping the peel with a knife (a tool not specialized for separating food), but not by using a peeler.
    Exception As on Shabbat, an action necessary to eat a food normally (derech achila) does not violate the prohibition of boreir. So you may peel a food that is normally separated from its peel or shell in order to be eaten, as long as you do not use a specialized instrument to do so.
Examples
  • You may peel an orange by hand, with or without a knife.
  • You may remove the shells from peanuts by hand.
  • You may remove the shell from a hard-boiled egg by hand.
2. Do This Shortly before You Eat the Food
   Prepare the food soon before it will be eaten.
     Note       You may prepare the food as much in advance as you would normally prepare a meal which you will eat--even as much as several hours.
     Examples     
On Jewish festivals, you may:
  • Remove fish bones from fish while you are eating the fish or just before eating it.
  • Cut open a melon such as a cantaloupe and remove any seeds normally.
Introduction to Shabbat: Meals
Three Shabbat Meals
We are required to eat three Shabbat meals, as a rabbinic (d'rabanan) enactment to enjoy Shabbat (oneg Shabbat). The first Shabbat meal must be at night and the remaining two must be during the day (the third meal must be eaten after halachic midday). Friday night dinner and the first meal on Saturday are preceded by kiddush. For the first two Shabbat meals, say ha'motzi over two complete loaves of bread, each of which is at least 1.3 fl. oz. in volume. For the third meal, the ideal is to use two complete loaves of bread, but the requirement of eating the third meal can also be fulfilled by eating any food other than salt or water.

Source of Saying Shabbat Kiddush
  • Saying kiddush on Shabbat night is a commandment from the Torah (d'oraita).
  • Saying kiddush on Saturday morning is a rabbinical (d'rabanan) enactment.
Note If you did not say Friday night kiddush, you must say that version of kiddush on Shabbat morning and it is then a requirement from the Torah (d'oraita). Do not begin with va'yechulu; instead, begin with borei pri ha'gafen and say the second blessing of kiddush.

Source of Kiddush Location
Saying kiddush at the place where you will eat your meal is a rabbinical (d'rabanan) enactment.

Shabbat Kiddush-Meal Quantities: Evening
  • For evening kiddush, a minimum of 4 fl. oz. (119 ml) of wine must be blessed on and at least half must be drunk.
  • For the evening meal, as on Shabbat lunch and all required Jewish festival meals, a minimum of 1.9 fl. oz. of bread must be eaten within four minutes.

Shabbat Kiddush-Meal Quantities: First Meal on Saturday
Shabbat day first meal has two separate eating requirements.  They may be combined (say/hear kiddush and start the main meal right away) but are often done separately (say/hear kiddush and then eat some mezonot; the main meal is eaten later in the day).
Note Since eating and drinking requirements on all morning kiddushes (both Shabbat and Jewish festivals) are d'rabanan, the required beverage amount for morning kiddush is only 3.3 fl. oz. (99 ml) instead of the d'oraita 4 fl. oz. (119 ml), which is required for kiddushes for Shabbat evening.
1) Morning kiddush requires a halachically legal “meal” with these elements:
      a) Blessing on a minimum of 3.3 fl. oz. (99 ml) of wine (or other beverage),
      b) Someone's drinking at least 2 fl. oz. of the beverage, followed by
      c) Eating at least 1.3 fl. oz. (39 ml, or 1/6 cup) of some type of mezonot (or bread) within four minutes.
Note If you drink at least 3.3 fl. oz. (99 ml) of wine within 30 seconds, you do not need to eat mezonot.
Note You do not need to drink the wine or other kiddush beverage to fulfill “establishing a meal.” You may hear kiddush and then simply eat the required amount of bread or mezonot. This applies to Shabbat or Jewish festivals, evening or morning.
The kiddush “meal” does not have to satiate.
Note If you have not fulfilled the requirements for kiddush, you may not eat other foods, such as fruit or fish at a kiddush.

2) The real meal (kovei'a se'uda) of Shabbat lunch requires eating at least 1.9 fl. oz. (56 ml) of bread (or matza during Passover!) within four minutes. It should include enough food to satiate.
Note You can simultaneously fulfill the requirement to “establish a meal” and to “eat a meal” by eating one (the same) piece of bread.
For details on fulfilling the first two meals' requirements, see Shabbat: Kiddush.

Shabbat: Eating a Meal Requirement: Third Meal
For details on fulfilling the third meal's requirements, see Shabbat: Third Meal (Se'uda Shlishit).
Flying through Shabbat for Business
If you fly through Shabbat (permitted for business only), you must keep even Shabbat d'rabanan while flying over the area of the earth that is in Shabbat.
If you fly east (such as from Asia to the US, across the Pacific) after Shabbat is over, you will re-enter Shabbat and may not do melacha on the airplane. Say the Shabbat prayers and kiddush at the appropriate local time where you are flying.
 
Human Dignity (Kavod HaBriot)
Although human dignity (kavod ha'briot) cannot override Torah commandments, kavod ha'briot allows violating some d'rabanan laws in order to avoid embarrassment.
Examples
  • Tearing Toilet Paper
    Situation You need to use toilet paper on Shabbat but none is torn.
    What To Do You may tear some toilet paper using any non-standard method or change from the normal way (shinu'i), such as not using your hand, or dropping something on the paper.
  • Hearing Aid
    Situation You may speak to someone who uses a hearing aid on Shabbat to avoid embarrassing him or her.
Introduction to Shalom Bayit
Shalom bayit is a family at peace, as one unit. When leniencies in law are used to avoid intrafamily conflicts, customs and d'rabanan halachot can sometimes be overridden. But d'oraita halachot may not be violated. Consult a rabbi.
Situation
You want to go to minyan but your wife is overwhelmed with trying to feed several children and she asks you to help.
What To Do
You must miss minyan and help her since your wife's needs take precedence over your wish to pray with a minyan.
Note With shalom bayit problems between spouses, a rabbi should be consulted for details.
Note Once someone is married, his or her in-laws are part of his or her family and are included in shalom bayit rules.


 



Baking in Non-Kosher Oven
An oven that has not been used for at least 24 hours is considered, d'oraita, to be neutral/pareve, but only if it is clean. D'rabanan, it is still not kosher, but this may be useful for when you can be lenient; e.g., if there is a safek.
100 Blessings on Weekdays
Try to say 100 blessings a day.  This is easy on weekdays since Ashkenazim say about 89 blessings just in the prayer services.
NoteSaying 100 blessings each day is a halacha drabanan.
Shabbat: Talking about Weekday Subjects
You may talk about weekday subjects on Shabbat if what you are discussing already happened, but you may not discuss plans to do activities that involve any type of melacha, even d'rabanan.
Jewish Festivals: Talking about Weekday Subjects

You may talk about weekday subjects on Jewish festivals if what you are discussing already happened, but you may not discuss plans to do activities that involve any type of melacha, even d'rabanan.

How to Prepare Food in a Non-Kosher Kitchen

BAKING IN NON-KOSHER OVEN

An oven that has not been used for at least 24 hours is considered, d'oraita, to be neutral/pareve, but only if it is clean. D'rabanan, it is still not kosher, but this may be useful for when you can be lenient; e.g., if there is a safek.

Note Even when baking in a non-kosher oven, you must cook the food in a kosher utensil.

INTRODUCTION TO BAKING IN NON-KOSHER OVEN

Baking in a Non-Kosher Oven

How To Tell if Oven Is Clean

To determine whether a non-kosher oven with black or brown spots is clean, scratch them:

  • If the substance crumbles, the spots are OK and you may bake non-liquid food in that oven without covering the food.
  • If the spots do not crumble or they remain immovable or come off in flakes rather than crumbles, consider the oven not clean.

Uncovered Food; Clean (Non-Kosher) Oven

You may cook food uncovered in a non-kosher oven if:
  • The oven rack and walls are clean, and
  • The food is not “liquid.”
    Note Non-liquid is defined as not being liquid before cooking OR not being liquid after cooking, but the food does not need to be non-liquid at both times.  Examples of “non-liquid” foods:
    • Apple cobbler
    • Lasagna
    • Meat (that will create gravy at the end)
    • Pudding
    • Raw fish.
Situation You plan to bake uncovered food in a clean, non-kosher oven in which the racks are not clean.
What To DoPlace two layers of foil under the baking utensil.

Double Wrapping

When To Double Wrap

Double-wrap food before baking in a non-kosher radiant-heat oven if:
  • The rack and/or oven are not clean;
  • The food that you are baking is liquid at any time during the cooking process; OR
  • Some of the food you are baking spills onto the rack or oven surfaces.

How To Double Wrap

When wrapping food for cooking in a non-kosher oven, the wrapping material does not need to seal completely, but the:

  • Food must be completely covered with two layers of foil or plastic;
  • Layers must keep water vapor out from between the layers; and
  • Surfaces of the utensil must all be covered.

SPILLED KOSHER FOOD IN NON-KOSHER OVEN

Kosher Food Spilling in Non-Kosher Oven

If kosher food spills inside a non-kosher oven in which you are cooking uncovered kosher food (whether liquid or non-liquid), consult a rabbi about whether the uncovered kosher food may still be eaten.

NoteIn this case, it makes no difference whether the oven is clean or dirty because the spilled food is wet and takes on the non-kosher status of the oven. When the spilled food vaporizes, it carries the non-kosher essence to the kosher food or utensil.
NoteIf the non-kosher oven had not been used for more than 24 hours, the food is probably still kosher b'di'avad
NoteThis applies to food spilled either from the same utensil in which you were cooking the kosher food or from a different utensil.

FROZEN FOOD IN NON-KOSHER OVEN

Double Wrap Frozen Food in Non-Kosher Oven

Frozen food is considered to be wet food regarding cooking it in a non-kosher oven or regarding its being neutral for dairy and meat issues: If the oven is not kosher, the frozen food must be double wrapped, even if the oven is clean.

AIRLINE MEALS IN NON-KOSHER OVEN

Heating Airline Meals in Non-Kosher Oven

Airline meals are usually non-liquid, so even if they are single-wrapped, it is OK to heat them in a non-kosher oven as long as no non-kosher food contacts the kosher food container.

COOKING IN NON-KOSHER MICROWAVE OVEN

Microwave Oven: Kosher Status

Introduction to Microwave Oven: Kosher Status

If a microwave oven's walls/floor/door do not become hot (more than 120° F, or 49° C), the microwave oven does not become non-kosher, dairy, meat, or non-Passover/chametz.

NoteA microwave oven that does not normally get hot, may get hotter than 120° F if you cook:

  • A liquid or moist food for a long time (even if less than 10 minutes),
  • Several liquid or moist items sequentially, or
  • Popcorn and similar foods.

If a microwave oven's walls/floor/door get hot, the oven can become dairy, meat, or non-kosher (if they become one gender and then the opposite gender is cooked or if non-kosher food has been cooked in it). If any surface--including walls, door, floor, etc.--that gets hot are plastic or coated metal, it cannot be returned to kosher or pareve. However, if the surfaces are all made of metal, they may be kasherable. Consult a rabbi.

NoteIf the microwave oven does get hot, it cannot be kashered at all--not for Passover and not from non-kosher to kosher. To check if your microwave oven gets hot, see How To Check If a Microwave Oven Will Get Hot during Cooking

Microwave Oven: Kosher Status: Walls and Door

Since microwave oven walls and doors do not normally get hot (more than 120° F, or 49° C), there is usually no need to kasher them from milk to meat (or back to milk); from ordinary use to Passover use; or from non-kosher to kosher. Just clean all surfaces.

Microwave Oven: Kosher Status: Floor

Microwave oven floors can get hot, especially where there is no rotating glass tray and the utensil is placed directly on the oven floor. All microwave ovens should be assumed to get hot unless you have tested them personally.

Microwave Floor

Cover the floor (ideally with styrofoam or another substance that blocks heat and moisture) in a non-kosher microwave oven.

Glass Tray

The glass tray does not become non-kosher and does not become dairy or meat or chametz (unless it was removed and used in a conventional oven) as long as it is clean.

Plastic Tray Support

The plastic support under the glass tray must be cleaned and must be blocked from contact with actual cooking utensils and from food if the tray:

  • Has any food of the gender opposite that of the food being cooked,
  • Has non-kosher food on it, or
  • Is dirty and you cannot tell with what.

How To Check If a Microwave Oven Will Get Hot during Cooking

To determine if the walls of a microwave oven will get hot during cooking:

  • Boil water for as long as food would typically be cooked in that microwave oven, and
  • Touch the inside walls, floor, door, and ceiling
    • If the walls are too hot to touch, the walls may acquire the gender of any food cooked in the oven. (If the walls are already the opposite gender when cooking a food, the oven may become non-kosher.)
    • If the walls are not too hot to touch, then no change of status occurs.

Non-Kosher Microwave Oven: Hot Oven, Liquid or Solid Food

If the walls of a non-kosher microwave oven get hotter than 120° F, you must double wrap any liquid or solid food you cook in that oven.

NoteIf you did not double wrap liquid or solid food cooked in a non-kosher microwave oven, consult a rabbi about whether you may eat the food.

Non-Kosher Microwave Oven: Non-Hot Oven

If the walls of a non-kosher microwave oven stay less than 120° F, you do not need to wrap or cover liquid or non-liquid food, as long as:

  1. The microwave oven is clean and dry, and
  2. If the tray is non-glass or non-Pyrex, you put a layer of separation (plastic, styrofoam, etc…) that blocks heat and any moisture underneath the cooking utensil.

COOKING ON NON-KOSHER STOVE

Setting Down Hot Lid on Non-Kosher Stove Top

SituationYou set down a hot pot lid on a non-kosher stove top.
Status

  • Lid is dry and stove is clean: lid remains kosher.
  • Lid is dry or wet and stove is dirty: lid is non-kosher.
  • Lid is wet and stove had hot non-kosher mixtures on it within the previous 24 hours--even if the stove is clean: lid is not kosher.
  • Lid is dry or wet and stove is clean and did not have hot non-kosher mixtures on it within the previous 24 hours: lid is kosher.

COOKING WITH NON-KOSHER UTENSILS

Using a Non-Kosher Kitchen Utensil
Introduction to Using a Non-Kosher Cooking Utensil

You may not use a non-kosher cooking utensil (pot, pan, baking dish, etc.) for cooking even if the utensil is clean and has not been used for more than 24 hours (unless you kasher it first).

Fruit Cut with Non-Kosher Knife
You should wash most fresh fruit cut with a non-kosher knife in order to remove whatever non-kosher food might have been on the knife from before.
Note Fruit with a sharp taste—such as lemons or tart apples—may not be used if cut with a non-kosher knife, regardless of whether the knife had been used within 24 hours.

WASHING IN NON-KOSHER SINK

Using a Non-Kosher Sink
A dish is still kosher b'di'avad if heated to 120° F (49° C) or more in a clean, non-kosher sink that had remained below 120° F for the previous 24 hours.
 

Introduction to Jewish Festivals: Medicines
Jewish Festivals: Medicines: When To Take
Medicine generally may not be used on the d'oraita Jewish festival days.

Jewish Festivals: Medicine for Chronic Diseases
You may take medicine on Jewish festivals (whether d'oraita or d'rabanan) for:
  • Chronic diseases, such as Parkinson's disease, or
  • Any disease that affects your entire body.
Jewish Festivals: Medicine for Non-Chronic Diseases
You may take medicine on Jewish festivals for non-chronic illnesses, if skipping one day will prevent cure.  You may not take medicine for non-chronic illnesses if skipping a day will just delay your being cured (unless the disease affects your entire body--in which case, you may take the medicine).

Jewish Festivals: Medicines: When To Take: D'Oraita Festival Days
Here are the d'oraita Jewish festivals:
  • First day of Sukkot, Passover, and Shavuot
  • Seventh day of Passover
  • Shmini Atzeret (8th day of Sukkot)
  • Yom Kippur
  • Both days of Rosh Hashana (even though the second day is d'rabanan).
On these days, as well as on d'rabanan Jewish festivals, you:
  • MUST take medicine whenever there is any question of a life-threatening disease or condition.
  • MAY take medicine for a condition that affects the entire body (illness, weakness, etc.). Consult a rabbi if possible.
    ExceptionYou may not smear substances on skin UNLESS the illness is life-threatening, in which case even smearing is permitted.
  • MAY use some medicines if only part of your body is affected by a non-life-threatening disease--consult a rabbi.
Jewish Festivals: Medicines: When To Take: D'Rabanan Festival Days
You make take medicines for any reason on d'rabanan Jewish festivals--even medicines not allowed on the first day of Jewish festivals--except:
  • Medicines that you smear on skin.
  • If the Jewish festival falls on Shabbat (which can only be second day of Shavuot).
Note The d'rabanan Jewish festivals are the second day of Jewish festivals except Rosh Hashana (actually, the second day of Rosh Hashana IS d'rabanan but has the status of d'oraita), plus the last day of Passover and Simchat Torah outside of Eretz Yisrael.

Jewish Festivals: Squeezing, Dabbing, Smearing
As on Shabbat, you may squeeze a tube of cream on Jewish festivals, but you might not be able to use the cream on the Jewish festival for other reasons—consult a rabbi.
Note Smearing creams or ointments is permitted only in life-threatening situations. Otherwise, you may not smear cream on skin on a Jewish festival (or Shabbat) even using a shinu'i such as using the back of your hand or a toe.
Dabbing is permitted, but only when you are permitted to use medicine. 
Example
You may use cream on a Jewish festival (and Shabbat) by dabbing (you may ONLY dab--you may not SMEAR cream) for a bee sting if it will affect the entire body. You may not use cream for a mosquito bite, since it is only a local irritation.
Hot, Wet Taste Transfer in Countertops
A hot (120° F--49° C--or more), wet utensil transfers its gender to a countertop upon which it is placed, but only at the area of contact.
Status of Countertop
  1. Gender status of the countertop:
    • D'rabanan, the countertop area of contact remains that gender until kashered (as long as the countertop material is kasherable).
    • D'oraita, the countertop reverts to kosher-neutral/pareve after 24 hours.
    Note If the utensil and counter were not wet (nor dirty with food) at the area of contact, there is b'di'avad no transfer of gender.
  2. If you put a hot, wet utensil of the opposite gender on that same spot, that counter space may become non-kosher.
Status of Utensils
If the counter had not had a hot, wet utensil/container of food of the opposite gender placed on the same spot within 24 hours of each other, the utensils may be used and the utensils are still kosher.
Status of Food
This does not apply to food that is directly placed on the counter, in which case the food might become non-kosher.
