Here is a delicious recipe for lemonade made out of whey leftover from cheesemaking. Add 1/3 cup of honey and the juice of 2 lemons to 1 quart of whey. That’s it! I added a little boiling water to the honey and stirred it to make a syrup. Otherwise it can be impossible to get honey to dissolve in cold liquid. If your whey was still hot when you made it, you wouldn’t need to do that. You can also use sugar instead of honey if you like.
Anyway this stuff is really good and good for you because of the minerals and protein in the whey. I hear you can also add Tang or Kool-Aid but personally I would rather do the lemonade. There are so many things you can do with whey, including making awesome bread and pizza crust. You can also put it on your garden or give it to pigs and chickens but it almost seems like a waste because it’s so tasty for cooking and drinking.
