Kitchen answer
What is a good substitute for buttermilk?
Add 1 tablespoon of lemon juice or white vinegar to 1 cup of milk, stir, and rest 10 minutes.
What else to know
- Plain yogurt or sour cream thinned with milk also works one-for-one.
- The acid is what reacts with baking soda, so do not skip it in soda-leavened recipes.
