Gelatin is a common food thickener used in many culinary applications, including desserts, gummy candies, and marshmallows. It is a protein derived from collagen, which is found in the bones, skin, and connective tissues of animals. Gelatin is available in powder or sheet form and can be dissolved in hot liquid to create a gel-like substance. It is a versatile ingredient that can be used to create a range of textures, from soft and delicate to firm and chewy. Gelatin is also a good source of protein and collagen, which can have potential health benefits for skin, joint, and bone health.
