The Etrog is one of the symbols of Sukkot. It is a special fruit, which looks like a giant lemon and grows on very delicate trees. They grow in warm climates like Israel and Italy, and some Hassidim actually prefer the Etrogs from Italy (from the region of Calabria), because of a tradition that says that Moshe used one from there. A lot of people, after using their Etrogs in the Sukkot services, like to make jelly or other specialties with them at the end of the holiday. In the movie Ushpizin the protagonists use its juice to dress a salad, but here is another fun use for your precious etrog at the end of Sukkot… and you can make this recipe any time using regular lemons!
