Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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 absorbs butter and sauce as its starch structure sets during cooking.
- Butter
- Adds richness and a smooth mouthfeel to the drained macaroni.
- Stewed tomatoes
- Provide acidity and body to the sauce, balancing the savory gravy.
- Leftover bones and trimmings
- Release gelatin and flavour into the water, giving the sauce body and savoury depth.
The step that matters
Simmer the bone gravy until reduced. Reducing the liquid concentrates flavour and gelatin from the bones, so the sauce gains body instead of tasting thin and watery.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Tomatothe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
