Best Buttermilk Substitutes
Buttermilk brings acid and tang. Any substitute needs to bring both, or your baking soda has nothing to react with.
Milk plus acid
Add 1 tbsp lemon juice or white vinegar to 1 cup milk and rest 10 minutes. The closest everyday swap.
Yogurt or sour cream
Thin 3/4 cup plain yogurt or sour cream with 1/4 cup milk or water. Richer results, great in cornbread.
Kefir
Use one for one. It is already cultured and thin enough to pour.
Powdered buttermilk
Worth keeping in the pantry. Whisk the powder into your dry ingredients and add water for the liquid.
