Shabbat: Mixing Powders with Liquid

You may mix powdered food substances with liquids on Shabbat if:
  •  The resulting mixture will be fluid (you can pour it in a smooth and steady stream), AND
  •  You put whatever is normally added second into the container first and then add the component that is normally added first to the other substance, AND
  •  You mix it with your finger, not with a utensil.
Note You may not mix a powdered food substance with a liquid on Shabbat if it will result in a paste (such as wasabi).
