Why it works: Mozzarella cheese and parmesan cheese match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,093 recipes. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
Mushroom Appetizer
Ingredients
Directions
Make the filling
Melt butter in a large frying pan and add the onions and mushrooms, then saute until soft.
Add mozzarella, parmesan, parsley, egg, salt, and pepper. Cook for 1 minute and remove from heat.
Assemble and bake
Roll each crustless slice of bread to flatten it. Butter each piece and cut each slice into 4 square pieces.
Press bread pieces, buttered side down, into a tiny muffin tin.
Fill each bread cup with the mushroom mixture.
Cut the three cheese slices into 16 pieces each (48 pieces total) and place a piece on top of each tartlet.
Bake at 350°F for 20 to 25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Forms the crisp, buttery cup that holds the filling while it bakes.
- Mushrooms
- Supply savory, earthy bulk and moisture to the filling.
- Mozzarella cheese
- Melts into the filling to bind it and give a stretchy texture.
- Parmesan cheese
- Adds salty, savory depth and helps the filling brown on top.
- Egg
- Binds the cheese and mushroom mixture so it holds together in the cups.
- Butter
- Adds richness and helps the bread crisp and brown in the oven.
The step that matters
Pressing the buttered bread into the muffin tin. Buttered side down helps the bread crisp and brown into a sturdy cup; if the bread is not pressed firmly, the cup can slump and let the filling spill out as it bakes.
