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

What each ingredient does

Flour
Its starch swells when cooked, thickening the sauce and giving it body.
Tomatoes
Provide the main liquid, acidity and fruity flavor of the sauce.
Butter
Adds fat for richness and carries flavor while the onion browns.
Chopped onion
Browning in butter builds sweetness and savory aroma into the sauce.

The step that matters

Cook until there is no taste of raw starch. Flour starch must be heated long enough to swell and thicken the sauce fully. Undercooked flour leaves a raw, pasty taste, so keep simmering until it is gone before straining.

Flavor stand-ins for the onion

  2. Shallotbetter flavor fit
  3. Capsicumbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against tomato, parsley, butter, clove, allspice, flour, pepper. 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).
