I just went to Sbarro Pizza today after years. I ordered NY stile Pizza and Garlic Bread. Taste was very good. I ask for additional pizza sauce and they give me for free. This is the best Pizza Sauce i ever try.... very natural !
How can i make a similar pizza sauce ?
Sbarro uses a proprietary tomato product they have distributed in cans to their chains. Most of the major chains except for papa johns uses a heavy cooked down tomato paste with citric acid, dry garlic powder, high fructose corn syrup/sugar, spices (dry oregano, salt, pepper, basil). They are thinned with water at the restaurant.
A cooked down paste product which has a very high concentration of natural glutamate and then thinned with water produces a very different sauce than with canned crushed or fresh tomatoes. You could try using a paste product like Saporito Super Heavy. If using canned crushed tomatoes, a glutamate can be added, such as pork bones or anchovy filets in a light 20-30 minutes simmer along with other ingredients. Grated parmigiano reggiano is also another glutamate.
