Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mozzarella cheese
- Melts into a stretchy layer that binds the sandwich and gives it pizza-like richness.
- Italian bread
- Provides the sturdy outer structure that holds the fillings while toasting.
- Pepperoni
- Releases fat and savory flavor as it heats, seasoning the filling.
- Butter
- Promotes browning and a crisp, golden crust on the outside of the bread.
- Tomato
- Adds moisture and acidity that brighten the filling.
The step that matters
Toast on a hot griddle. Heat must brown the outside while melting the cheese inside. If the griddle is too cool, the bread absorbs butter and turns soggy before the cheese melts; if it is too hot, the crust burns before the center warms through.
Swap the garlic
