Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sourdough bread: Forms the outer shell that crisps and browns when grilled.
Mozzarella cheese: Melts into a stretchy layer that binds the sandwich together.
Provolone cheese: Melts smoothly, adding creaminess and a mild, savoury flavour.
Cheddar cheese: Melts to add richer flavour and a sharper taste.
Melted butter: Conducts heat and promotes golden browning on the bread surface.

The step that matters

Grilling the sandwich until the cheese melts. Pressing heat too fast can scorch the bread before the cheese melts through. Moderate heat lets the bread brown evenly while the cheese softens completely.
