A jelly donut is a type of fried pastry filled with sweet fruit jelly or jam. It is typically made from a yeast-based dough that is light and fluffy. After frying, the donut is often rolled in granulated sugar to enhance its sweetness. Common fillings include flavors like raspberry, strawberry, or grape, but other varieties exist. Jelly donuts are popular in many cultures and are often enjoyed as a treat during celebrations or holidays, such as Hanukkah in Jewish tradition. They can be found in bakeries and cafes around the world.
