Corn starch, derived from corn kernels, is a versatile ingredient commonly used as a thickening agent in various culinary applications. Its primary function is to enhance the consistency and texture of sauces, soups, and desserts by forming a gel-like substance when mixed with liquid and heated. This property makes it a valuable tool in both cooking and baking.

In the context of alcohol and cocktails, corn starch is less commonly used but can serve specific purposes. For instance, it can be employed to create syrups or to stabilize foams and emulsions in drinks. By thickening the liquid, it can help to achieve the desired mouthfeel and presentation, ensuring that the cocktail has a smooth and cohesive texture.
