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

What each ingredient does

Ox tails
Provide meat and gelatin that give the soup body and a rich, savoury flavour.
Butter
Fat that carries flavour and helps brown the joints at the start.
Onions
Add sweetness and aromatic depth as they soften during the long simmer.
Carrots
Add natural sweetness and body to the broth during simmering.
Turnips
Add mild sweetness and earthy flavour to the broth.
Port wine
Adds sweetness, depth and aroma, added at the end so its flavour stays bright.

The step that matters

Skim the surface. Skimming removes foam and fat that rise as the liquid first boils. Removing them early keeps the broth clear and clean-tasting over the long simmer.

Swap the onion

How well each one fits the dish's main ingredients (ham, butter, carrot, turnip, clove, sugar, port wine):

  1. Leekfits better
  2. Shallotfits better
