How to Make Buttermilk at Home

Easy Buttermilk Substitutes

You can easily make a buttermilk substitute with common kitchen ingredients. Here are the most popular methods:

1. The Milk and Acid Method
   • Add 1 tablespoon of white vinegar or lemon juice to a liquid measuring cup.
   • Pour in enough milk to reach the 1-cup line.
   • Stir gently and let the mixture stand for 5-10 minutes until it thickens and curdles slightly.
2. The Yogurt or Sour Cream Method
   • Mix 3/4 cup of plain yogurt or sour cream with 1/4 cup of milk or water.
   • Whisk until smooth and reaches a pourable consistency.

Important Notes

• This substitute works best for baking recipes that call for buttermilk.
• For best results, use whole milk, but low-fat milk will also work.
• The acid helps tenderize baked goods and activate baking soda.
