Buttermilk powder, also known as dry buttermilk or powdered buttermilk, is a dairy product derived from the liquid remaining after cream is churned into butter. This liquid undergoes spray-drying, a process that removes moisture and creates a fine powder. Retaining the characteristic tangy and slightly acidic flavor of traditional buttermilk, this powdered form is used in a variety of culinary applications, enhancing both the taste and texture of dishes.
