It's easy to make and is often used as a substitute for Buttermilk. While not 100% exactly buttermilk it will be similar and will have the acidity that a recipe may require especially for baking.Recipes with baking soda or baking powder that call for sour milk or buttermilk need the acidity to rise.

Instructions
To make exactly 1 cup of sour milk put 1 tablespoon of vinegar OR 1 tablespoon of lemon juice in a measuring cup and fill it up with milk until you get to the 1 cup mark. Give it a stir.
Let the mixture sit for 5 minutes so it can become soured and it's ready to use.

Notes
How to make 1/2 cup sour milk - Same process but use 1 1/2 tsp of vinegar or lemon juice and fill measuring cup with milk to 1/2 cup.How to make 1/4 cup sour milk - Same process but use 3/4 tsp (1/2 tsp plus 1/4 tsp) of vinegar or lemon juice and fill measuring cup with milk to 1/4 cup.IF you need the milk to curdle/thicken it should be room temperature or slightly warmed in the microwave on a low defrost setting. I'm not convinced this is needed. Not being cold could throw a recipe off also. If I find otherwise I'll update this post.How to make real homemade sour milk.This is how my grandma would make real sour milk.Pour one cup of milk into a clean bowl, cup or glass and let it sit out overnight to sour. No doubt this takes time but if you want real sour milk for baking this is they way to get it.
