Cold Buttermilk Soup Cold Buttermilk Soup is a refreshingly tangy and sweet soup, perfect for enjoying on a warm day. The creaminess of buttermilk combined with the sweetness of sugar and the aromatic hint of vanilla offers a delightful contrast of flavors. Typically served as a light dessert or a palate-cleansing appetizer, this soup is enhanced with the added crunch of corn flakes or toasted rolled oats on top. Not only is this a unique way to enjoy buttermilk, but it's also a conversation starter due to its unusual combination of ingredients that come together beautifully in each sip. Ingredients
