Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Macaroni
Forms the main body of the dish, giving it bulk and a firm, chewy bite.
Butter or olive oil
Carries the onion's flavour and adds richness to the sauce.
All-purpose flour
Thickens the sauce so it coats the macaroni instead of running off.
Strained tomato
Provides the sauce's base, adding acidity and savoury flavour.
Grated cheese
Adds salty, savoury flavour and helps the sauce turn rich and clinging.

The step that matters

Cook the onion until slightly brown. Browning the onion in fat develops sweeter, deeper flavour through the Maillard reaction. Taking it too pale leaves the sauce flat, while over-browning can make it bitter.

Swap the tomato

How well each one fits the dish's main ingredients (butter, onion, flour, cheese):

  1. Chivefits better
  2. Potatofits better
  3. Mustardfits better
  4. Tomatothe original

Fit is the average pairing score against butter, onion, flour, cheese. Candidates are from the same food group and used in at least 100 recipes.
