If you don't have buttermilk don't worry. You can make your own at home as long as you have either white vinegar or lemon juice. To make 1 cup of buttermilk you will need 1 tablespoon of the acid (either the vinegar or lemon juice) paired with just shy of 1 cup of milk. Let it sit for 5-10 minutes until it starts to curdle. Mix and then use to make buttermilk pancakes!
