Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Long simmering breaks down connective tissue, giving the stew body and richness.
- Beef
- Slow cooking tenderises the meat, while its juices add savoury depth to the broth.
- Carrots
- Add natural sweetness and body to the stew as they soften during cooking.
- Onions
- Frying until browned builds sweet, savoury flavour that deepens the stew.
- Cornflour
- Starch thickens the liquid into a smoother, glossier sauce when stirred in.
- Port wine
- Adds sweetness, depth and aroma to the sauce.
The step that matters
Removing the fat before thickening. Fat rises and pools on the surface of a long-simmered stew, and leaving it in makes the sauce greasy. Skimming it off first lets the cornflour thicken a clean, well-flavoured liquid.
