Challah is actually made in various shapes and sizes depending on the occasion, but the most traditional is the three strand loaf. The strands intertwining one another are meant to symbolize love and each strand represents truth, peace, and justice. Round loaves are baked for Rosh Hashanah, the Jewish New Year. Since a round loaf has no beginning and no end, it is meant to represent the continuity of a year. Raisins are sometimes added and the top can be brushed with honey to symbolize a sweet new year.
