Crust!!We do the same,,sorta!!
When we lived in Philly I remember that the best pizza ever was a "White Clam Pizza"
So I make my own,
Bobali crust
Fresh block of Parmesan cheese
Garlic
salt and pepper
can of clams (drained)
garlic Alfredo sauce
Italian spices
I make the pie,brush on some virgin olive oil, sprinkle some spices and what ever and throw it in the oven until the edges just start to lightly brown
pull it out and sprinkle the cheese on some garlic sprinkle and return to the oven just until the cheese starts to melt
take it back out,, swirl the Alfredo sauce on and spread a can of clams on top!
return and cook until the edges are a nice golden brown!!
Not an exact science, but for a time reference, this is usually a three beer job!!
EDIT: Opps,, wife pointed out I forgot about the other cheeses,,I use cheddar (mild) and light Mozzarella or Monterrey Jack depending on what I brought!!
