Easy Guide: How to Make Buttermilk from Milk at Home

Making buttermilk at home is a simple process that only requires two common ingredients – milk and an acidic component. There are various methods to make a substitute for buttermilk if you don’t have any on hand. One method is to combine 1 tablespoon of white vinegar or lemon juice with enough milk to measure 1 cup, and let it sit for 5 minutes. Another option is to use 1 cup of plain yogurt as a substitute for 1 cup of buttermilk. If you follow a dairy-free diet, you can use coconut milk or soy milk instead of regular milk.
