Thanks Scott,
You confirmed something as well as I did myself last night.I made a plain cheese Ny style pie and used whole milk mozz only.No part skim or shredded from the bag.
I shredded the mozz myself.It was a wal mart great value brand,nothing fancy but I like it.When slices of the pizza were folded the orange oil began to drip out.I was ecstatic.When the slices were left out for a while,it took on a very orange oily appearance,which confirmed it more.Of course by that time,the pizza gets a little old tasting and possibly too oily,but was glad to see that using this cheese alone created the look and taste I was looking for.
I didn't have puddles,just a few drops at a time but the pie tasted really good.I used Red crushed tomatoes with basil,garlic,oregano,with no oils added.
When Im down to the rim of the crust,I find myself trying to soak up the oil up with it before finishing.

Gonna try some other brand cheeses as well when I can find them in the stores.
