Leftover Buttermilk

If you have buttermilk left over from a recipe, it’s safe to freeze it, but be sure to use it within 3 months for best flavor. An alternative is to buy a handy powdered mix called Saco Cultured Buttermilk Blend, which is found near dry and canned milk in the grocery store. You can reconstitute the quantity needed for your recipe in seconds. The remaining dry mix will keep in your refrigerator for up to 2 years—saving you a trip to the store the next time you need buttermilk.
