Can buttermilk be frozen successfully?

Question

Can I freeze unused buttermilk bought at the supermarket for later use? Can it later on be thawed and used safely?

Answer 1

Yes, you can freeze buttermilk.

When thawed, the emulsion will break into solids and whey. This makes no difference for baked goods; you can also use a blender to restore it to a smooth, thicker liquid if needed for applications like salad dressing.
