What is a food that starts with the letter U?

Unleavened bread is a food that starts with the letter U. It is bread made without yeast. Unleavened bread, also known as matzah, is closely associated with the Jewish holy day of Passover.

Unleavened bread, or matzah, is used as part of the Passover celebration to commemorate the haste at which the Israelites fled from Egypt. Because the Israelites escaped their bondage in Egypt with such speed, they did not have time to permit their bread to rise. The Bible instructs the Jewish people to eat unleavened bread for a period of seven days as part of the overall celebration of Passover.
