Jelly is a sweet preserved form of fruit that's usually made with sugar. Your favorite breakfast might be buttered toast spread thickly with strawberry jelly.
Jelly is the close relative to jam and preserves — jelly is typically more translucent than its fruitier cousins, and is sometimes made with juice rather than whole pieces of fruit. Outside of North America, jelly is a dessert made from gelatin. Jelly comes from the Old French gelee, "jelly" and also "frost," from the verb geler, "to congeal," with its Latin root gelare, "to freeze."
