I'll give vodka a try tonight and see if I pass out or if it makes the pizza taste different j/k - (I've got an extra dough ball ready to go and sauce made up in the fridge one "normal" size can of sauce two "small" cans paste, chopped fresh basil, pinch onion salt, pinch garlic salt, pepper, chipotle spice and soon splash of vodka).
My wife makes a Vodka pasta and that sauce would be AWESOME on a pizza with lighter flavor toppings like chicken and veggies.
Didn't think about trying it with pizza till now, I'll get back with some results.
