How to Sour Milk to Sub for Buttermilk

When a recipe calls for buttermilk but you have none, you can easily make sour milk to substitute for buttermilk. The flavor difference between buttermilk and sour milk will be undetectable in the dish. With a quick and simple addition to regular milk, it will curdle and turn sour almost before your eyes. You can then finish your recipe, complete with the required sour milk.

Things You'll Need

• 1 cup regular milk
• 1 tbsp. lemon juice or white vinegar
• Glass measuring cup
• Spoon

Instructions

1. Measure 1 cup of milk into the glass measuring cup. Add 1 tbsp. of lemon juice or white vinegar to the regular milk and stir the two ingredients to combine them.

2. Allow the mixture to stand for 15 minutes. During this time, the milk will begin to curdle.

3. Stir the milk one more time after 15 minutes elapses. The milk should appear curdled in the measuring cup.

4. Add the sour milk to your recipe in place of the buttermilk.
