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 the sauce as its starch structure stays firm when cooked until tender.
Tomatoes
Provide the main liquid and acidity that form the body of the sauce.
Lard
Adds fat that gives the sauce a richer mouthfeel and rounds its flavour.
Grated cheese
Adds savoury, salty flavour and a little fat to the dish.
Onion
Adds aromatic sweetness and depth to the simmered tomato sauce.

The step that matters

Simmering the sauce slowly for 2 hours. Long, gentle simmering lets the tomatoes thicken and their flavour concentrate. Without enough liquid the sauce can scorch or dry out, which is why water is added when it gets too dry.

Swap the onion

How well each one fits the dish's main ingredients (cheese, tomato, pepper, parsley, egg):

  1. Capsicumfits better
  2. Carrotfits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against cheese, tomato, pepper, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
