I made this for the Jewish holiday of Sukkot, which celebrates the harvest season. I used my standard challah recipe (Recipe #252369), but replaced the water with various vegetable purees. So the harvest colors of the loaf complemented the theme of the holiday perfectly! I can also picture making just the beet and spinach colors for a festive red and green Christmas wreath bread for my Christian friends! This recipe makes 12 loaves, but could easily be reduced. There are 4 separate batches of bread dough, one for each color. Then you divide each into strips and braid one of each color together in 4-strand braids.
