When to Make Your Own Buttermilk

I love the flavor that buttermilk adds to recipes like pancakes, scones, and of course buttermilk biscuits. Sometimes I realize that I forgot to pick up buttermilk at the grocery store. Or what I had is actually way past the expiration date and I’m quickly in need of a homemade buttermilk substitute.

We’ve all been there. Mid-recipe you realize that the ingredients call for buttermilk and there’s none in the refrigerator. You’re stuck googling things like how to make buttermilk or buttermilk substitute.

And you’re hoping that you can still salvaged your already started recipe. No one wants to make a special trip to the grocery store for just one item, so occasionally you have to make do with a buttermilk replacement.

For those type of situations it is nice to have this kitchen tip for how to make buttermilk up your sleeve. With common ingredients, you can easily make homemade buttermilk to use in your recipes.

How to Make Buttermilk 6 Ways

Out of buttermilk? No worries! Some of these buttermilk substitutes are easier than others in a pinch. My most commonly used method is to make homemade buttermilk with milk and lemon or vinegar, but the others are helpful as well.

Most of the methods for homemade buttermilk that I’ve outlined below start with regular milk (whole milk works best), so you’ll need to at least have that on hand.

Cream of Tartar Buttermilk Substitute

Wondering how to make buttermilk from milk? It couldn’t be simpler!

Measure 1 3/4 teaspoon cream of tartar plus 1 cup milk. Whisk to combine and let stand at room temperature for 5-10 minutes, until curdled and then stir. The mixture then becomes your buttermilk replacement — use the same measurement you need for your given recipe.

Lemon Juice Buttermilk Substitute

To make your own buttermilk using lemon juice,  you are going to add 1 tablespoon of lemon juice to a liquid measuring cup. Then, add regular milk (whole milk works best) until the amount reaches one cup.

Let the milk and lemon juice mixture stand at room temperature for 10 minutes. The milk should look curdled after about 10 minutes. Stir and you have a homemade buttermilk subsitute to use in your recipe!

Alternatively, if you don’t have fresh milk, you can combine 1/3 cup powdered milk + 1 cup water. Then, add 1 tablespoon fresh lemon juice. Let sit for 10 minutes before using.

Plain Yogurt Buttermilk Substitute

Another way to make buttermilk at home is the following: 2 tablespoons of regular milk plus enough plain yogurt to equal one cup. Whisk well to combine and you have a buttermilk substitute. Then, use as your recipe instructs.

If you are using plain GREEK yogurt, you’ll want to use 3 – 4 tablespoons of milk because Greek yogurt tends to be a bit thicker than plain traditional yogurt. Either type of yogurt works well as a buttermilk substitute.

Sour Cream Buttermilk Substitute

Sour cream can also be used as a buttermilk substitute. It is pretty similar to the method for using plain yogurt. However, I add slightly more milk since sour cream tends to be thicker than plain yogurt (unless you’re using Greek yogurt).

To make a sour cream buttermilk substitute, combine 3-4 tablespoons of regular milk plus enough sour cream to equal 1 cup. Whisk well to combine and you have a buttermilk substitute. Stir to combine and then use your as your buttermilk subsistute in your recipe.

White Vinegar Buttermilk Substitute

This method for making a buttermilk replacement is identical to the lemon juice buttermilk substitute, except you’re going to use white vinegar instead.

To make a buttermilk substitute using white vinegar, add 1 tablespoon of white vinegar to a liquid measuring cup. Then, add milk until the amount reaches 1 cup. Let the mixture stand at room temperature for 5-10 minutes.

It should look curdled. Stir and you have homemade buttermilk for your buttermilk substitute!

Alternatively, if you don’t have fresh milk, you can combine 1/3 cup powdered milk + 1 cup water. Then, add 1 tablespoon white vinegar. Let sit for 10 minutes before using.

Buttermilk Powder Buttermilk Substitute

Buttermilk powder is buttermilk that has been pasteurized, then concentrated with an evaporator, and then dried to produce a powder. You can purchase buttermilk powder at most any grocery store.

To make buttermilk using buttermilk powder, follow the instructions on the buttermilk powder container. The instructions on the buttermilk powder that I have state to combine 1 cup of water with 1/4 cup powder to equal 1 cup of fresh buttermilk.

Bonus Buttermilk Substitute

Depending on the recipe, I have used canned coconut milk as a substitute for the buttermilk.

BUT you have to use your personal discretion on this one because the flavor is certainly different, plus some recipes need the acidity of buttermilk (or one of the substitutes mentioned above) to react with the leavening agent.

Tips for Making Buttermilk Replacements

If you’re trying to make buttermilk from milk (i.e. adding lemon juice or vinegar to it), whole milk is best. Skim milk doesn’t contain nearly enough fat or flavor to work as a buttermilk substitutes. In a pinch, 2% milk should work, but whole is best.

If you don’t have white vinegar on hand, do not try to substitute another vinegar that has a strong flavor. For example, you can NOT make homemade buttermilk with something like balsamic vinegar.

Lastly, you need to give all of these buttermilk substitutes time to curdle. Wait a good 10 minutes or so before adding the homemade buttermilk into your dish. If you don’t wait the full 10 minutes, your buttermilk substitute may not work.
