*What can I substitute for buttermilk?
Often, home cooks will sub in milk mixed with lemon juice or vinegar when they run out of buttermilk. However, modern buttermilk is actually made from cultured milk, rather than the leftover liquid from making butter. That means that an even better substitute for the buttermilk you'd most likely have on hand is mixing plain yogurt into milk. For this recipe, we'd suggest 1 cup of milk and 1/4 cup of yogurt.
