What if you don’t have buttermilk?
If the store is out of buttermilk, we can make our own by combining 2 ½ tablespoons lemon juice or distilled white vinegar with 2 ½ cups whole milk. Let the mixture stand for five to 10 minutes, and our buttermilk substitute is ready. Don’t substitute regular milk. As mentioned, we need buttermilk to get the right texture.
