The first portion of your kneading, you shall separate as a dough offering (challah)... (Numbers 15:20-21)

In its more widely-known usage, the Hebrew word challah refers to the Shabbat bread. But in its more basic, biblical and halachic meaning, challah is the piece of dough that is traditionally separated and consecrated to G‑d every time we bake bread.

The Separation of Challah is one of the three primary mitzvot of the Jewish woman and has a far-reaching effect on the mind and heart of the one who fulfills it, on her family, and on the very character of her home.
