Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb or beef shoulder
- Connective tissue breaks down slowly into gelatin, making the meat tender and the broth rich.
- Onion
- Builds savoury sweetness and aroma as it softens in the broth.
- Carrots
- Add natural sweetness and body to the stew.
- Potatoes
- Release starch as they cook, adding body to the broth.
- Tomatoes
- Add acidity and flavour that balances the rich meat.
- Flour
- Starch thickens the liquid into a smoother, heavier stew.
The step that matters
Cook slowly for 2 hours. A gentle simmer lets connective tissue in the shoulder break down into gelatin, which keeps the meat tender. Boiling hard tightens the muscle fibres and leaves the meat tough and stringy.
