What Happens When You Freeze Buttermilk?
When you freeze buttermilk, the liquids separate and the texture changes. The liquid may become slightly grainy and the buttermilk may thicken. However, the flavor should remain the same and it can still be used in recipes such as baked goods, pancakes, and sauces. It is recommended to thaw frozen buttermilk in the refrigerator overnight and shake well before using.
