A gelatin sponge is a soft, porous material made from gelatin, a substance derived from collagen found in animal bones and skin. It is often used in various applications, including medical and culinary fields. In medicine, gelatin sponges can serve as a hemostatic agent to help control bleeding during surgeries. In the culinary world, gelatin sponges are used to create light, airy desserts and can be flavored or colored to enhance their appeal. They are typically made by whipping gelatin with air, resulting in a fluffy texture that can be molded into different shapes for presentation.
