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 enjoyed by many. Jello is often used in recipes for layered desserts, salads, and even cocktails. It is a favorite at parties and gatherings, especially for children, due to its fun texture and vibrant colors. Additionally, it can be a low-calorie treat, making it appealing for those watching their diet.
