So you bought buttermilk to make a particular recipe, and you used that cup, and now…you have the rest of the container and need to use it up! You’re not going to throw it away, oh no, not you — you’re not a wasteful person. But what else to use it in? Luckily, it’s incredibly versatile. There are lots of ways to use up leftover buttermilk.
Buttermilk is particularly great in pancakes, biscuits, creamy salad dressings, cornbread, banana bread, cakes, Irish soda bread, and lots of baked goods. You can substitute buttermilk for milk (and other dairy products) in many baking recipes with a 1:1 ratio. It works best if there is at least 1/2 teaspoon of baking soda in the recipe. If there is only baking powder, you can replace 1/2 teaspoon of the baking powder with baking soda, and then use your buttermilk instead of milk.
Leftover buttermilk can be frozen in an airtight container for up to 3 months.
