jello

Jell-O is a brand of gelatin dessert products produced by Kraft Heinz. Gelatin desserts are prepared by dissolving a flavored gelatin powder in hot water, then adding cold water and refrigerating until the mixture sets into a firm gel. The result is a sweet, wobbly dessert with a distinct texture.

The name Jell-O is widely used to refer to gelatin desserts in the United States, though it is a registered trademark. The brand originated in the United States in the late 19th century; Jell-O was introduced in 1897 by the Genesee Pure Food Company and later came under Kraft Foods (now Kraft Heinz) through corporate acquisitions.

Jell-O comes in many flavors and forms, including sugar-free varieties. It is commonly served as a dessert, and is also used in decorative molds or as part of layered dishes and fruit-containing salads sometimes referred to as Jell-O salads.

The dessert is made from gelatin derived from animal collagen, mixed with sugar or artificial sweeteners, flavorings, and colorings. Because it uses gelatin, it is not suitable for vegetarians or vegans, although plant-based gelling agents such as agar are used in other products. Gelatin desserts must be refrigerated to set and should be kept cold according to package directions.
