Leftover whey from cheese
1/4 cup vinegar
1 gallon milk
LEFTOVER WHEY VERSION: Turn on fire and bring on the heat! I don't stir, I just walk off. You'll notice clumps and bits heading to the top. Drain into cheesecloth lined colander.
MILK VERSION: Heat milk until almost boiling, remove from heat and add vinegar. It should separate. Drain into cheesecloth lined colander.
Can be frozen and used later. Fantastic for lasagna or stuffed shells.
