what is a citron

A citron is a large, fragrant citrus fruit with a thick rind. It is one of the original citrus fruits from which all other citrus types developed through natural hybridization. The citron fruit is usually ovate or oblong, narrowing towards the stylar end, and the rind is leathery, furrowed, and adherent. The inner portion is thick, white, and hard, while the outer part is uniformly thin and very fragrant. Some citrons have medium-sized oil bubbles at the outer surface, and some varieties are ribbed and faintly warted on the outer surface. The fruit is used in various culinary applications, including making pickles and in holiday fruitcakes. It is also used in religious rituals, especially during the Jewish harvest holiday of Sukkot. The citron is not primarily used for eating like a lemon or an orange, as it has very little pulp compared to other citrus varieties
