The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Tripe
Forms the main body of the dish and gives it a chewy, tender texture after long simmering.
Onions
Soften during cooking and add sweetness and savoury depth to the liquid.
Milk
Adds creaminess and body to the sauce, mellowing its flavour.
Flour
Starch thickens the milk and cooking liquid into a smooth gravy.

The step that matters

Mixing the milk with the flour before adding it. Flour mixed into hot liquid forms lumps because the outer layer of each starch granule gels before the inside can hydrate. Blending the flour fully into cold milk first lets the starch disperse evenly, so the gravy thickens smooth.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (milk, flour, celery):

  1. Arrowrootfits better
  2. Carrotfits better
  3. Parsnipfits better
  4. Onionthe original

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