Hello there! I would be more than happy to explain how to make a reliable buttermilk substitute for your pancakes.
You will need one cup of milk and one tablespoon of white vinegar or lemon juice. Simply pour the vinegar into a measuring cup, then add enough milk to reach the one-cup line.
Stir the mixture gently and let it sit undisturbed at room temperature for about five to ten minutes. You will notice it starts to curdle slightly, which means the acid has reacted with the milk and created a great substitute for your pancakes.
