Buttermilk is an amazing ingredient for pancakes, cakes, and even fried chicken but it is so annoying to keep on hand. Most recipes require only a little and those big cartons expire in the blink of an eye! Well worry not because this super-easy buttermilk substitute works perfectly in all your recipes.
Buttermilk is a great ingredient in all sorts of recipes because its acidity reacts with leavening agents for fluffier cakes, tenderizes meats, and of course added moisture. Unfortunately, those cartons it’s sold in will not keep in the fridge very long and it’s so disappointing when you’re halfway through a recipe and realize your buttermilk is bad or you forgot to buy it in the first place!

Why is buttermilk good in recipes?
Buttermilk is thicker and more acidic than regular milk. The acid reacts with leavening agents like baking soda and powder to create fluffier cakes, muffins and even soda breads! If you’re marinating something like chicken in buttermilk the acid helps to tenderize the meat. It also has a slight tang that adds some depth or flavor to dishes, often balancing out the sweetness in a cake, etc.
How to Make Buttermilk
1. For a cup of buttermilk you’ll need about a tablespoon of an acid. You can squeeze some lemon juice or open a bottle of white vinegar.
2. Pour the lemon juice or vinegar into your milk. You’ll immediately notice some curdling but there’s just a little more to do to let’s move forward!
3. Give the buttermilk a quick stir to distribute the acid you added.
4. For baked goods like cakes, pancakes, and muffins I usually just set the milk aside for 10 minutes so it has a bit of time to finish curdling but if you’re using this for a fried chicken, or dressing recipe and want that nice uniformly thick consistency give it a good shake in a jar. Now you have a buttermilk substitute that works in any recipe!
Now you can make all those delicious recipes like these fluffy buttermilk pancakes in a snap!
