How to Make Sour Milk
Have you ever started to make a recipe and realized that the recipe calls for buttermilk and you don’t have any? I know I have! It’s not only annoying, it’s frustrating. Next time, instead of leaving everything sitting out on the counter, jumping in your car and driving like a bat outta hell to get to the store. Try making your own buttermilk (sour milk). It’s easy to do and if you have milk in your refrig half the battle is already won. The next time a recipe calls for buttermilk, keep calm and try one of these substitutes.
Buttermilk is used in recipes because it’s more acidic than milk. This allows buttermilk to react with ingredients such as baking soda or baking powder to produce carbon dioxide bubbles. Buttermilk is a key ingredient in soda bread, because of it’s different chemistry. It’s also used exclusively in homemade velvet cakes too. You can use any kind of milk to make buttermilk. When you add an acidic ingredient to milk, it causes the milk to curdle.
You can make your own buttermilk from 2 %, 1 %, or skim milk. Use any acidic ingredient such as lemon juice, white vinegar or any cultured dairy product, such as; sour cream or yogurt to curdle milk and produce buttermilk. Allow 5 to 10 minutes for the ingredients to react with each other. Once the milk curdles, you have buttermilk. You can use the mixture right away or refrigerate it for later but use it within 24 hours.
