How do you make sour milk?

You don't need to make sour milk! It's a natural process that happens when milk goes bad. Here's how it works:

* Bacteria: Milk contains naturally occurring bacteria. When milk sits out at room temperature, these bacteria multiply.

* Lactic acid: As the bacteria grow, they break down lactose (milk sugar) into lactic acid. This acid is what gives sour milk its characteristic tangy flavor.

* Curdling: As the acidity increases, the milk proteins (casein) start to clump together, creating the curdled appearance.

Here's how to tell if milk is sour:

* Smell: Sour milk has a distinctly sour, tangy smell.

* Taste: Even a small sip will reveal the sour taste.

* Appearance: The milk may have a slightly thicker consistency and may have separated into curds and whey.

You can use sour milk in baking recipes like pancakes and muffins, but it's not safe to drink!

If you want to speed up the process of souring milk, you can add a tablespoon of plain yogurt or buttermilk to your milk and let it sit at room temperature for a few hours.
