When we were in Rome last summer I made it part of my mission to sample as much pizza as possible. It was one of those dirty little tasks that someone just had to do, besides, it made 2/3 of my trip a business expense.
What I found was a much sweeter sauce on a much thinner pizza than I expected.
For my own personal pizzas, not those sold in our Pub, I will add a couple of teaspoons of sugar to about 3 ounces of our sauce, dribble in maybe a tablespoon of water (we don’t add any to our normal sauce) and then use that to sauce a 12" dough. Yes I suppose there is a bit of extra coloration of some of the exposed sauce, but it doesn’t impart a “burnt” taste at all, I actually like it, to me it’s more authentic than a typical belt baked pizza…if that makes any sense.
