Many of us have a tendency toss food as soon it reaches it's labelled expiration date, but there's still a lot of use left in that food. If you have some milk that's beginning to sour, you can still cook with it as if it were buttermilk.

It might sound a little off-putting, but Dana Gunders, the author of the Waste-Free Kitchen Handbook, suggested to NPR that you can give that funky milk another shot at becoming something tasty:
Actually, cooking with sour milk is delicious. It's a substitute for buttermilk. You can [use it] in pancake or biscuit batter. And you can't taste the sour! I've pushed it, and let the milk get really old. The pancakes turned out fluffy, and really good... Next time you give the sniff test and you're on the fence about it, use it as you would buttermilk in pancakes, waffles and other baked goods. It's amazing how you won't taste even the slightest bit of bitterness.
Gunders notes, however, that there is still a limit. If it's a clotted, bitter liquid that's really starting to separate, just toss it out. Still, this little trick might just help you use up the rest of your milk without having to waste it. If you know you won't be able to use your milk for a while, though, toss it in the freezer before you leave.
