How to Make Buttermilk

I have a favorite muffin recipe that requires buttermilk.  I typically don't keep milk in the house at all because I think it slows mucous functionality.  However,  I'm willing to buy some for my favorite muffins.  If you need milk for some other delicious recipe, it might be best to just make your own homemade buttermilk.

Very simple recipe for this one.

Buttermilk:
1c regular milk
1 tbsp. white vinegar

Simply mix the two together and let sit for about 5 minutes or so.

Then you can use the rest of your milk for non buttermilk related activities!  Notice Glee on my laptop in the background :)
