Buttermilk is crucial in classic recipes like ranch dressing, fried chicken, and pancakes, but almost no one has it when they need it. Hereโs How to Make Buttermilk at home with just two ingredients and 10 minutes.

As a classically-trained chef, I have studied all the ways buttermilk enhances recipes: juicier meats, fluffier baked goods, and sharper, more flavorful sides and sauces.
The trouble is, I never have it on hand. Iโm reluctant to buy it because I probably wonโt use it all. Buying a carton of buttermilk at the store is an exercise in optimism, but deep down I fear some of it will get thrown away.
The solution is simple, budget-friendly, and waste-conscious: make your own buttermilk. If you have milk and an acid and just 10 minutes, you can make the buttermilk you need and move on with your life.
