Why it works: Butter and bread 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 ↓
Macaroni Cheese
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Boil the macaroni in just enough water to allow it to swell until tender and the water evaporates.
Butter a pie dish and add a thin layer of bread crumbs.
Assemble
Layer the macaroni, then layer the cheese.
Season with salt and cayenne between the layers.
Repeat the layers.
Top with bread crumbs.
Add the remaining butter cut into small pieces.
Bake
Bake in a 400°F (200°C) oven until brown or use a salamander to heat thoroughly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish, giving the baked layers their body and chew.
- Parmesan cheese
- Melts into the layers to add savoury flavour and a binding, creamy richness.
- Butter
- Adds fat for richness and helps the top crumbs brown in the oven.
The step that matters
Boil the macaroni in just enough water. Using only enough water lets the pasta absorb it as it cooks, so the macaroni stays tender and the dish is not waterlogged. Excess water left in the pot would dilute the cheese and make the layers soggy when baked.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
