Switching from clarified butter to whole butter will result in a sauce with a richer, creamier texture and a more pronounced buttery flavor due to the presence of milk solids and water. However, it will also have a lower smoke point.
Clarified butter, also known as ghee, is butter that has had its milk solids and water removed. This process leaves behind pure butterfat, which has a higher smoke point and a cleaner, more subtle buttery flavor. When you use clarified butter in a sauce, you get a stable emulsion that can withstand higher temperatures without burning. The flavor is delicate and allows other ingredients to shine.
Whole butter, on the other hand, contains milk solids and water in addition to butterfat. These components contribute to a richer, more complex flavor profile and a creamier texture. The milk solids add a subtle sweetness and depth, while the water helps to create a smoother emulsion. However, the presence of milk solids also means that whole butter has a lower smoke point than clarified butter, making it more prone to burning at higher temperatures. Using whole butter will result in a sauce that is more intensely buttery and has a silkier mouthfeel.
When using whole butter in a sauce, keep the heat low to prevent the milk solids from burning and separating. You can also whisk in a small amount of acid, such as lemon juice or vinegar, to help stabilize the emulsion and prevent the sauce from breaking.
