Step 1: Ingredients
1: Plain Tomato Paste
2: American Mustard
3: Barbecue Sauce
Step 2: Mixing the Sauce
For every tablespoon of tomato paste, add one teaspoon of American Mustard and one teaspoon of Barbecue sauce. For a single pizza you'll likely need no more than three tablespoons of tomato paste and three teaspoons each of mustard and barbecue sauce.
Mix well with a tablespoon.
Slather onto your pizza as desired!
It's a very simple sauce, but it adds a little zing that makes it stand out against most plain tomato-paste based pizzas.
