What roles does food play at Jewish festivals, ceremonies and homes?
Food plays a significant role in Jewish festivals, ceremonies, and in Jewish homes. For example one Holy time that many Jewish people and even non-Jewish people keep (Christian churches that hold to Old Testament Laws) is the Passover. Food plays a major role in homes of those who partake of the Seder Dinner.
The Passover celebrates the Israelites escaping Egypt to freedom. The first night of Passover commences with the Seder -a ceremonial dinner. Wine is part of this meal. In addition, during the Passover season, unleavened bread is eaten. Lamb, eggs, fruit/nut paste, bitter herbs, and parsley or watercress are also part of the Seder Dinner at Passover time.
The Feast of Tabernacles (Sukkot, Feast of Booths) is another festival that Jewish and some Christian people observe. This is a seven day festival. Many types of food are eaten during this festival. Among these are many stuffed foods such as stuffed peppers, eggplants, cabbage, as well as stuffed fruits and pastries. Knishes, kreplach, and main-dish pies can also be a part of the Feast of Tabernacles meals. Leavened bread is eaten during this festival; there is no restriction stipulating that unleavened bread must be eaten. The Feast of Tabernacles or Feast of Booths is a reminder to Israel that they were sojourners in the land (Leviticus 23).
