How do you mix milk and vinegar for buttermilk?

While you can use milk and vinegar to substitute for buttermilk in recipes, it doesn't technically create buttermilk. Here's how it works:

* Buttermilk is a fermented milk product. It's made by adding bacteria to milk, which causes it to sour and thicken.

* Milk and vinegar, however, create an acidic milk mixture. The acid in the vinegar causes the milk proteins to curdle, mimicking the texture of buttermilk.

Here's how to make a buttermilk substitute:

1. Start with 1 cup of milk.

2. Add 1 tablespoon of white vinegar or lemon juice.

3. Stir well and let the mixture sit for 5-10 minutes. The milk will thicken and become slightly clumpy.

This substitute works well in most recipes that call for buttermilk, but it won't have the same tangy flavor as real buttermilk.

For a more authentic buttermilk flavor, you can use cultured buttermilk, which is readily available in grocery stores.
