Is there a substitution for buttermilk?

Answer 1

Yes, add one teaspoon of vinegar into one cup of milk; for instance, I use cider vinegar.

Let the vinegar/milk mixture set for a couple minutes and milk will curdle a bit and become sour to give it the buttermilk taste needed in the recipe.

Answer 2

For each cup of buttermilk you need, measure 1 tablespoon of vinegar into a measuring cup, then add enough regular milk to make 1 cup.
