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

What each ingredient does

Ox tails
Release gelatin and collagen as they simmer, giving the broth body and a silky mouthfeel.
Onions
Add savoury sweetness and aromatic depth as they soften and release flavour into the broth.
Carrots
Contribute natural sweetness and aromatic depth to the simmering broth.
Turnip
Adds mild sweetness and earthy flavour to the broth as it cooks.
Port wine
Adds sweetness, fruity aroma and depth to the finished broth.
Vinegar
Adds acidity that brightens the broth and balances its richness.

The step that matters

Skim off any foam. Foam carries impurities from the meat and vegetables to the surface. Skimming it early keeps the broth clear and clean-tasting, while a hard boil would churn it back in and cloud it.

Swap the onion

How well each one fits the dish's main ingredients (pepper, carrot, turnip, vinegar, port wine):

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

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