Why it works: Mozzarella cheese and romano cheese share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 62 recipes. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
Gourmet Grilled Cheese Sandwiches
Ingredients
Directions
Prepare the baste
Melt the butter over low heat in a small saucepan.
Whisk in the mustard and garlic when the butter is melted.
Set aside the butter-mustard-garlic mixture.
Assemble the sandwiches
Preheat the grill to medium-high (or about 350°F to 400°F).
Grate the three cheeses into a small bowl and combine with a fork.
Place 4 slices of sourdough bread on a large plate.
Add 1 tablespoon of scallions to each slice.
Spread a layer of cheese over the scallions, dividing equally among the slices.
Place a slice of sourdough on top of the cheese and brush the garlic-mustard-butter baste on top.
Place each sandwich, basted side down, on the grill.
Brush the tops of each sandwich evenly with the remaining garlic-mustard-butter baste.
Grill and serve
If using a 2-sided contact grill, grill for 3 to 4 minutes.
If using a hibachi, combination, or infusion grill, grill for 6 to 8 minutes (3 to 4 minutes on each side).
Remove from grill and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and helps the bread brown and crisp in the pan.
- Fontina cheese
- Melts smoothly and adds creamy, stretchy body to the filling.
- Mozzarella cheese
- Adds stretch and moisture so the filling binds when melted.
- Parmesan, asiago or pecorino romano cheese
- Contributes savory, salty flavour that deepens the cheese filling.
- Dijon-style mustard
- Adds sharp acidity that cuts through the rich cheese and butter.
- Sourdough bread
- Provides a sturdy, tangy structure that crisps on the outside while holding the filling.
The step that matters
Basting the tops before the grill. Butter fat browns the bread through the Maillard reaction, so an even layer gives even colour and crispness; patchy basting leaves pale or soggy spots.
