Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
Prepare the base
Mix the grated bread, grated Parmesan cheese, butter, egg yolks, nutmeg, and pepper in a bowl.
Spread the mixture over the bottom of a baking dish.
Add the eggs and cook
Place the dish over gentle heat to create a gratin.

Sprinkle additional Parmesan cheese over the surface.
Finish cooking until set and brown the top using a salamander or broiler.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm, custardy layer that holds the gratin together when cooked.
- Parmesan cheese
- Adds savoury flavour and helps the top brown and form a crisp crust.
- Egg yolks
- Add richness and a smooth, creamy texture to the base.
- Butter
- Adds fat for richness and helps the crumbs toast golden.
- Grated bread
- Provides body and soaks up moisture, giving the base a light crumb structure.
The step that matters
Finish cooking until set and brown the top using a salamander or broiler. Egg proteins set at moderate heat and turn rubbery if overcooked, so the eggs should be removed as soon as the whites firm. Browning the top needs intense heat applied briefly, so watch closely to avoid scorching.
Swap the nutmeg
How well each one fits the dish's main ingredients (bread, parmesan cheese, butter, egg, pepper):
- Parsleyfits better
- Nutmegthe original
- Sagefits about as well
- Capersfits about as well
Fit is the average pairing score against bread, parmesan cheese, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
