This mixture curdles and becomes slightly thicker, resembling the tangy flavor and consistency of buttermilk. Another option is to mix 1 and 3/4 teaspoons of cream of tartar with 1 cup of milk. These alternatives work well in baking and cooking, providing similar results to using actual buttermilk.
