One 16" skin weighs about 460 g, of which about half a pound is flour
I pay $18 for a 50 lb of All Trumps, but I'm guessing you're paying less for Sam's. Does $14 sound about right?
$14 / 50 lb. = .28/lb.
= .14/ 1/2 lb.
That same skin uses about 1/4 t. yeast
I pay $5 for 1 lb. of ADY which gives me 142 1/4 t. servings
$5 / 142 = .04/serving
2% oil translates into about a teaspoon's worth. I use soybean oil for NY style pizza, but, if I were using evoo, I pay $2 for a 90 t. container
$2 / 90 = .02
Salt, even sea salt, isn't going to cost more than a couple cents.
Grand total:
22 cents for one 460 g dough ball.
