"Salt Fat Acid Heat" is a cooking framework popularized by Samin Nosrat in her book of the same name. It emphasizes the four essential elements that contribute to delicious food: salt enhances flavor, fat adds richness and texture, acid balances and brightens dishes, and heat is the method of cooking that transforms ingredients. By understanding how to manipulate these four components, home cooks can create well-balanced meals. The approach encourages experimentation and intuition in the kitchen, allowing individuals to develop their culinary skills and confidence while making informed choices about ingredients and techniques.
