Final answer:
During Passover, leavening agents or grains that can become leavened, known as chametz, cannot be used. Matzoh is eaten instead. Meat products, dairy products, fruits and vegetables are permitted, following kosher laws and if they are not mixed with chametz.
Step-by-step explanation:
During the Jewish festival of Passover, leavening agents or grains that can become leavened are not used. This is to commemorate the Israelites leaving Egypt in haste, not having time to let their bread rise. The main prohibited foods are known collectively as chametz, which includes anything made from wheat, barley, rye, oats, or spelt that has not been completely cooked within 18 minutes after coming into contact with water. Instead of leavened bread, Jews eat matzoh, which is unleavened bread.
The other options listed, such as meat products, dairy products, and fruits and vegetables, can be consumed during Passover, provided they adhere to other kosher laws and are not combined with chametz or used in a way that violates specific Passover laws. Moreover, the depiction in Figure 16.5.1 from the Golden Haggadah illustrates some of the Passover preparations, including the cleansing of the house from leavened bread and the distribution of matzoh and haroset, which shows the historical and cultural practices surrounding this festival.
