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 and Cheese
Ingredients
Directions
Cook the macaroni
Break the macaroni into 1-inch pieces and blanch in boiling water for 10 minutes.
Strain the macaroni and add the shallot and hot milk; cook until the macaroni absorbs all the milk.
Assemble and bake
Remove the shallot and layer the cooked macaroni in a buttered dish with grated cheese, pepper, salt, and butter.
Repeat layers until all ingredients are used, finishing with cheese, a little cayenne, and fine bread crumbs on top.
Bake in the oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk and body of the dish, holding the sauce in its starchy structure.
- Hot milk
- Becomes the sauce as the pasta absorbs it, giving the dish its creamy moisture.
- Grated cheese
- Melts into the milk to add richness, savoury flavour and a stringy, creamy texture.
- Butter
- Adds fat for richness and helps the top brown in the oven.
- Shallot
- Infuses the milk with a mild onion-like aroma, then is removed before layering.
The step that matters
Cook until the macaroni absorbs all the milk. If the milk is not fully absorbed the dish stays soupy, while overcooking dries the pasta and the sauce can turn grainy or greasy. Watching the liquid as the starch swells keeps the texture creamy.
Swap the shallot
How well each one fits the dish's main ingredients (butter, cheese, milk, bread, pepper):
- Potatofits better
- Capsicumfits better
- Tomatofits better
- Shallotthe original
Fit is the average pairing score against butter, cheese, milk, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
