Definition of the word mix in

The phrase "mix in" originated in the mid-20th century, specifically in the context of cooking and food preparation. Its initial usage can be traced to the famous food critic and cooking instructor, Julia Child. Child, a pioneering figure in French cuisine in America, often used this colloquial term while demonstrating her cooking techniques on TV. She would instruct her viewers to "mix in" ingredients while preparing batters or doughs, rather than simply stirring them in or folding them gently. The term "mix in" carries a more casual and informal tone compared to "stir in" or "mix thoroughly"; it is often used when partially blending ingredients instead of completely integrating them. The phrase has since then gained popularity in cooking shows, cooking classes, and even everyday conversations, as more people began to adapt Child's easy-to-follow methods. In summary, the phrase "mix in" originated in the context of cooking as a more laid-back alternative to more technical culinary terms, and has since then become a commonly used expression in the kitchen and beyond.
