How to Make Buttermilk
Buttermilk is versatile - it can help tenderize a cake or add a fresh zing to a smoothie. But it's not an ingredient we usually have on hand. Don’t drop everything and race to the grocery store when you can make your own with just two very common ingredients.
All you need is whole or 2-percent milk and fresh lemon juice or white distilled vinegar.
Pour the milk into a liquid measuring cup.

Use the thickened milk — curds and all — just as you would buttermilk in your recipe. It's great for pancakes, salad dressing, fried chicken, coleslaw and more!
