I'm new around here, but have been reading up on other good "ideas". I've been attempting to make a good pizza for a few years now and have found a sauce I really like (my crust still has a ways to go).
My sauce is really quite simple. I just use canned whole tomatoes, remove the seeds, a can of tomato paste, salt, thyme (or oregeno if desired), white wine (Chardonnay usually), and a hint of balsamic vinegar (which intensifies the tomato flavor). Mix it in a blender, package and put it in the fridge overnight.
If I want a stronger sauce for pepperoni pizza, I use Tony Chachere's instead of salt.
I have to try better tomatos now, normally I just use the major store brands, but from what I have been reading so far, it seems there are far better ones to be had.
