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

What each ingredient does

Tomatoes
Provide the main body, acidity and flavour of the sauce.
Onions
Brown slowly to add deep, sweet, savoury colour and flavour to the sauce.
Butter
Carries the browning of the onions and adds richness.
Flour
Mixed with the onions and stock to thicken the sauce.
Rich stock
Adds liquid and savoury depth, loosening the thickened onion mixture into a sauce.

The step that matters

Browning the onions until very dark. Onions cooked slowly in butter caramelise, developing deep sweet and savoury flavour. Stopping early leaves a flat, raw taste, while burning gives bitterness.

  4. Onionthe original

Fit is the average pairing score against tomato, clove, garlic, parsley, allspice, butter, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
