now, at Costco, you get 18 eggs for what? $3?
now, a large egg is 1.75ounces
but the yolk is .75 ounces
which leaves a white of only 1 ounce per egg.
so you get 18 ounces of egg white for $3.
that comes to what? about 15 cents an ounce
AND YOU have to do all the work.
Mate, I think you should rethink the math.
Egg whites at Costco are a bargain
