C'mon guys! I was just trying to tell you how hot it was. Oh, go try it, but don't blame me when the HOT coffee floods out of the cup and onto your leg.
Egg shells are alkaline, while coffee is acidic. When added to coffee, the egg shells remove much of the bitterness and mellow out the flavor. Egg shells are also used in making campfire coffee – boiling loose grounds in a pot of water – because the shells help keep the grounds in the bottom of the pot.
If the egg shell still has an egg in it; well, you get protein with your coffee!
