Jello is a popular dessert made from gelatin, a substance derived from collagen found in animal bones and skin. It is typically sweetened and flavored, coming in a variety of colors and tastes. When mixed with hot water and allowed to cool, it forms a wobbly, jelly-like consistency that is fun to eat. Jello is often served in individual cups or molded into shapes using special containers. It can be enjoyed on its own or used as a base for other desserts, such as fruit salad or whipped cream. Its unique texture and vibrant colors make it a favorite at parties and celebrations.
