How To Make Buttermilk Substitute is an incredibly easy and quick way to make a homemade substitution right at home with just 2 ingredients!
How To Make Buttermilk Substitute is a must-save and share post that you’ll turn to when your refrigerator is missing a bottle of the real stuff! I’m guilty of scanning recipes, seeing an ingredient I don’t have on hand, and turning away.
Easy, quick substitutes like this one have allowed me to continue making recipes even after I find an ingredient I don’t have within reach!
I prefer using this substitute for buttermilk in baking whereas recipes like fried chicken, such as my Air Fryer Nashville Hot Chicken, or drinks, like Blackberry Buttermilk Panna Cotta, should use the real thing. This is because the real flavor of buttermilk is an important standout taste in those recipes!
What Is Buttermilk?
Buttermilk was the leftover milky liquid after churning cream into butter. Today it’s more of a cultured milk product that has lactic acid making baked goods perfectly fluffy and airy!
This popular ingredient is used in baking recipes, known for creating rich and tender cakes, muffins, and quick bread! The use for buttermilk doesn’t stop in the oven though, it’s also used for drinks, frostings, and in many breakfast foods!
This homemade buttermilk substitute is easily made using just two ingredients that you likely have on hand! For this recipe, I used fat milk such as 2% or whole milk, and an acid like lemon juice or white wine vinegar.
Don’t have either acid but still need a buttermilk substitute? No problem! Swap it out for a 1 3/4 teaspoon of cream of tartar!
Another common way is using plain greek yogurt as an equal part substitute. Since that’s a fairly thick buttermilk substitute, you can also mix 3/4 cup of sour cream with 1/4 cup of milk for a thinner option.
As you can see, you don’t need to instantly give up when you read that a recipe calls for buttermilk when you don’t have it within reach! You’re now well equipped with handy kitchen tricks to quickly and easily replace the real stuff with an alternative that works just as well!
