What Happens When Heavy Whipping Cream Freezes?
When heavy whipping cream freezes, the water in it forms ice crystals, which can cause the cream to separate and become grainy. When thawed, the cream may appear curdled or lumpy and will lose its smooth consistency and texture. The fat may also separate from the liquid, resulting in a less creamy and more watery product. It is best to use frozen heavy cream for cooking or baking rather than using it as a whipped topping.
