Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox cheek
- Slowly cooked, its connective tissue turns to gelatin, giving the broth body and the meat tenderness.
- Rice
- Its starch releases during cooking and thickens the broth slightly while adding bulk.
- Onions
- Their sugars brown and soften during boiling, adding sweetness and savoury depth to the stock.
- Sweet herbs
- Aromatic compounds infuse the water, giving the broth a fragrant, herbal character.
- Cow-heels
- Rich in collagen, they add gelatin that gives the broth a fuller, silkier mouthfeel.
The step that matters
Boiling the ox cheek. Vigorous boiling toughens meat and can leave the broth cloudy. A gentle simmer lets collagen slowly break down into gelatin, so the meat becomes tender and the stock richer.
