Why do we bake round challos for Rosh Hashanah?
Answer:
The challah of Rosh Hashanah is sweet, symbolizing the sweet year that we wish Hashem to give us.
It is made round to symbolize the circle of the life and the cycle of a new year.
The challah is also in the shape of a crown, indicating the coronation of Hashem on Rosh Hashanah, which is the central theme of the day.
Best wishes.
