Sukkot is a harvest holiday celebrating the harvesting of vegetables and grains. While there is not much symbolic food, there is a lot of symbolism in the way food is eaten during this week-long holiday.
Eating in the sukkah:
The word sukkah means “booth” or “hut.” During sukkot, it is symbolic ot eat meals in a sukkah to remember the forty years of wandering in the desert that the Jews enduring after leaving Egypt.
It is customary on sukkot to invite guests for meals to welcome people to your abode.
An etrog is a large cirtus fruit that looks like a lemon. While you don’t eat this during sukkot, I’ve heard of jams, marmalades and other excellent dishes made after the holiday ends. One interpretation is that the etrog symbolizes the heart and is shaken with 3 plant species (palm symbolizing the backbone, willow representing lips and myrtle referring to the eyes) and to show all the different people and strengths a community needs to flourish.
