Why your homemade buttermilk is just watered curd (and what real buttermilk actually is)

Many Indians dilute curd with water, calling it buttermilk, but true buttermilk is a fermented liquid left after churning butter. This traditional drink offers significant probiotic benefits for digestion and gut health, unlike simple diluted curd. While diluted curd provides refreshment and a lighter option, it lacks the active bacteria found in authentic buttermilk.
