Why it works: Butter and parmesan cheese are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,163 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

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 and gives it a firm, chewy structure once cooked.
- Parmesan cheese
- Adds savory depth and helps the sauce turn thick and creamy.
- White sauce (béchamel)
- Provides a smooth, creamy base that binds the cheese into the sauce.
- Tomato puree
- Adds moisture and bright, acidic tomato flavor between the pasta layers.
- Butter
- Adds richness and fat, carrying flavor and giving a smooth mouthfeel.
The step that matters
Cooking the macaroni until soft. Pasta cooked past tender keeps softening in the dish, so it can turn mushy. Draining it well also keeps excess water from thinning the layered sauce.
Swap the tomato
How well each one fits the dish's main ingredients (butter, parmesan cheese, sauce):
- Tomatothe original
- Asparagusfits about as well
- Onionfits less well
- Potatofits less well
Fit is the average pairing score against butter, parmesan cheese, sauce. Candidates are from the same food group and used in at least 100 recipes.
