Buttermilk contains curds, which makes it thicker than traditional milk. When making buttermilk at home, you can use whole cow's milk and an acid to make the fat in the milk form into curds, which simulates commercial buttermilk. Once you make your own homemade buttermilk, you can use it in recipes that call for buttermilk. Save time and money by making your own buttermilk from cow's milk at home.
Pour 1 cup of milk into a medium bowl.
Add 1 tbsp of white vinegar to the milk. Stir until the vinegar mixes well with the milk.
Allow the solution to set for five minutes.
Add the required amount of the buttermilk you've made to the recipe.
Store any leftover buttermilk in an airtight container.
Replace the vinegar with fresh lemon juice if you do not have vinegar on hand.
