Does sweetmilk have to clabber to make buttermilk?

Yes, sweet milk can be clabbered to create buttermilk. Clabbering occurs when milk is left at room temperature to sour and thicken due to the action of bacteria. This process produces a tangy, thicker product similar to traditional buttermilk. However, commercial buttermilk is typically made by fermenting low-fat milk with specific cultures, so the results may vary slightly.
