Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox cheek
- Provides rich meat and gelatin that enrich the broth during long, gentle cooking.
- Brown flour or roux
- Thickens the soup and gives it a deeper, toasted flavour and body.
- Vegetables
- Fried in fat first to build savoury, browned flavour that carries into the broth.
The step that matters
Cook gently for 4 to 5 hours. A gentle simmer breaks down the tough connective tissue in the cheek into gelatin, giving body and tenderness. A hard boil toughens the meat and makes the broth cloudy.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (flour, pepper, rice, bread, ham, mushroom, onion):
- Shallotfits better
- Capsicumfits about as well
- Asparagusfits about as well
- Tomatothe original
Fit is the average pairing score against flour, pepper, rice, bread, ham, mushroom, onion. Candidates are from the same food group and used in at least 100 recipes.
