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

What each ingredient does

Ox-tails
Long stewing breaks down connective tissue, making the meat tender and gelatinous.
Flour
Starch thickens the gravy as it heats, giving it body.
Carrots
Natural sugars add mild sweetness and body to the gravy.
Turnips
Starchy flesh softens during cooking and adds earthy flavour and body.

The step that matters

Stew until tender. Ox-tail is rich in connective tissue that only turns tender and gelatinous after a long, gentle simmer. Cutting it short leaves the meat tough, so it needs the full time at a low, steady heat.

Swap the onion

How well each one fits the dish's main ingredients (clove, madeira wine, sauce, pepper, carrot, turnip, flour):

  1. Shallotfits better
  2. Parsnipfits better
  3. Leekfits better
  4. Onionthe original

Fit is the average pairing score against clove, madeira wine, sauce, pepper, carrot, turnip, flour. Candidates are from the same food group and used in at least 100 recipes.
