How to Make Buttermilk Substitute and 5 Great Recipes That Use Buttermilk

If you have ever craved warm buttermilk biscuits but lacked buttermilk, we are going to show you how to make buttermilk with just a few simple ingredients. Buttermilk was originally the byproduct of churning butter—the leftover liquid filled with cultures that gave it its distinctive tartness.

Today, buttermilk is more like kefir that is created by adding friendly bacteria to pasteurized milk. Old-fashioned buttermilk was essentially fat-free because all of the fat was in the butter, but modern buttermilk can be purchased as skim or even full-fat.

When making buttermilk at home, you have the ultimate freedom to choose whatever percentage of fat you prefer. For a rich and creamy buttermilk, use whole milk—or even whole milk with a touch of cream added. For a lighter version try 1% or 2% milk, or whatever milk you have on hand.

What Does Buttermilk Do?

Buttermilk, because of its slightly acidic nature, imparts a unique flavor to foods, but buttermilk also helps with the leavening and texture. Most recipes that call for buttermilk will also include baking soda as the primary leavening agent. The acidity of buttermilk balances baking soda’s naturally alkaline compounds.

It is important to note that substituting plain milk in a recipe that calls for buttermilk will leave a lot to be desired. You really do need to use buttermilk in recipes that have been formulated for it.

How to Make Buttermilk

Let’s start with a traditional buttermilk recipe. This is no substitute—it’s the real deal! (You do need a kitchen thermometer.) And as a bonus, you’ll end up with 1 pint of buttermilk and 8 ounces of fresh butter!

Traditional Buttermilk Method

Ingredients

  • 4 cups heavy cream (not ultra-pasteurized)
  • 1 cup plain yogurt with live cultures
  • 1/2 teaspoon Kosher salt

Instructions

  1. Heat 4 cups of cream in a large saucepan over low heat until the cream reaches 70℉.
  2. Scoop 1 cup of plain yogurt into a bowl and pour the just warmed cream over the top. Stir until smooth.
  3. Cover the mixture tightly and let rest on the kitchen counter for 24 hours. The buttermilk base will thicken overnight.
  4. When you are ready to make your buttermilk (and butter), pour the buttermilk base into your food processor bowl outfitted with the metal blade.
  5. Secure the lid and process on high for 6 to 9 minutes, or until little bits of butter start to form.
  6. Strain the mixture through a fine-mesh sieve into a large bowl or saucepan. Let the butter solids rest and continue to drain for at least 10 minutes. Press the mixture gently with the back of a clean spoon to extract more buttermilk.
  7. Pour the drained buttermilk into a glass jar, seal with a tight-fitting lid, and refrigerate.
  8. Now, while the butter is still in the sieve, rinse it thoroughly under cold running water until the water runs clear. Pull together the bits of butter into a ball or lump and set aside.
  9. Add 1 cup of ice cubes and 3 cups of water to a large bowl. Submerge the ball of butter in the ice water bath and knead it to release the last traces of buttermilk.
  10. When the ice water gets cloudy, toss the water and start with fresh water and ice cubes again. You may have to change the ice water bath two or three times until the water remains clear.

Congratulations! You now have butter. If you prefer unsalted butter, wrap the butter in plastic wrap and stash it in the refrigerator.

If you prefer salted butter, place the butter on a cutting board and sprinkle it with a 1/2 teaspoon of Kosher salt, and then knead it together. Take a taste of the butter, and if you feel it needs more salt, add a touch more.

Wrap the salted butter in plastic wrap and keep it in the refrigerator until you are ready to use it.
