Buttermilk is one of those things that I seem to always need, but never have on hand! That's partially because I have a lot of trouble finding it in stores for some reason! Is anyone else with me??
But it's alright BECAUSE making buttermilk yourself couldn't be any easier! All you need is regular milk and an acid, and you're all set.
But you may be wondering: why do I even need buttermilk in the first place? Well, first it helps to sort out what buttermilk does in baking!
What is buttermilk?
Buttermilk is basically a more acidic and thicker type of milk. Its main use in baking is to make things more tender, and it also provides a slightly tangy flavor. The acid in the buttermilk adds wonders to batters that use baking powder because they react together to give you a much lighter and airier final product.
If you want to do an experiment, take a muffin or cake recipe that uses milk, and swap it out for buttermilk. Right off the bat, the batter will have significantly more bubbles, and the final product will rise higher and the inside will look airier!
Vinegar Versus Lemon Juice
When making your homemade buttermilk, you need to add an acid to it. You can use either white vinegar or freshly squeezed lemon juice as your acid. Both work perfectly.
The difference? Absolutely nothing. We're only using 1 tablespoon, so you're not going to get any major flavor from either one.
I typically prefer to use vinegar as my acid
because I'm too lazy to wash, cut, and squeeze a lemon ... just because. But if you don't have vinegar on hand, lemon juice does the exact same job. It's my go to backup!
Homemade buttermilk should be used within 10 minutes of being made! It's not going to be nearly as stable as store bought buttermilk, so the longer it sits, the more the milk will start to curdle.
