What Is It Called When You Mix Butter Flour And Milk?
The process of mixing butter, flour, and milk is called making a white sauce or béchamel sauce. It is a classic French sauce used in many recipes as a base for other sauces or gravy. The mixture is cooked over low heat until it thickens and becomes a smooth, creamy sauce, which can be seasoned with salt, pepper, or other ingredients according to the recipe.
