Buttermilk is crucial in classic recipes like ranch dressing, fried chicken, and pancakes, but almost no one has it when they need it! Here’s how to make buttermilk at home with just two ingredients and 10 minutes.
For every 1 cup of whole or 2% milk, stir in 1 tablespoon lemon juice. Let the mixture stand for 10 minutes.
Milk: To make dairy-free buttermilk, substitute an equal amount of almond milk, coconut milk, oat milk, or soy milk.
Lemon juice: Or substitute lime juice, white vinegar, or apple cider vinegar.
Yield: This recipe makes about 1 cup of buttermilk.
Storage: Store covered in the refrigerator for up to 2 weeks. Stir or shake to recombine before using.
Make buttermilk with yogurt: Combine 3/4 cup plain yogurt with 1/4 cup milk.
Make buttermilk with cream of tartar: Stir together 1 cup of whole or 2% milk and 1 3/4 teaspoon cream of tartar. First, mix the cream of tartar with 2 tablespoons of milk to form a loose paste; this keeps the cream of tartar from forming lumps. Then, add the rest of the milk.
