What is the minimum measurement of dough for taking Challah?
The requirement to separate Challah (and recite a blessing) from a dough is only when it contains the volume (not weight) of at least a tenth of an Aifah – 43 and 1/5 Kabeitza (eggs) – of flour.
Converting this measurement into weight depends on many factors, such as: the type of flour (whole wheat, all-purpose flour, high gluten, other types of grain, etc.), moisture content, sifting, and seasonal changes.
In practice, when using regular white (wheat) flour1:
- 59 ounces of flour or more: One should separate, with a blessing.
- Between 43 and 59 ounces: One should separate. Some say it should be done without a blessing, but many are lenient and make a blessing even with this amount.
- Less than 43 ounces: Challah is not separated.
In all amounts mentioned above, one should avoid the margin of error, by using more or less flour.
|59 ounces:||3 lb. 11 oz. (3.6875 lbs.)||1.666 kg||About 12 1/3 cups of flour|
|43 ounces||2 lb. 11 oz. (2.6875 lbs.)||1.230 kg||About 8 2/3 cups of flour|
