How many times have you found yourself in desperate need of Southern-style biscuits, but without the requisite buttermilk in the fridge? Or there’s the other scenario: You have a hankering for Nashville hot chicken, but you’re reluctant to buy an entire carton of buttermilk when you only need a cup.

For either situation, I have a solution: It’s easy to make a very quick buttermilk substitute in less than 10 minutes. The closest buttermilk substitute is milk with a spoonful of lemon juice or white vinegar.

Why Do We Need Buttermilk Anyway?

Whether we’re talking pancakes or quick breads, the role of buttermilk in almost any baking recipe is to add tenderness and lighten the batter.

Making a Substitute for Buttermilk

If we don’t have buttermilk in the fridge, the closest substitute would be another dairy product with a little acidity added; milk with a spoonful of lemon juice or white vinegar does the job quite nicely.

This mixture won’t get as thick and creamy as buttermilk, but it will perform its role in the batter just as well. Incidentally, yogurt or sour cream thinned with milk (or plain water, in a pinch) also work well as buttermilk substitutes.

Thank goodness for buttermilk substitutes, because a good pancake craving should never go unsatisfied.
