Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tails
- Provide the meat and collagen that become tender and rich during long stewing.
- Flour
- Thickens the gravy so it coats the meat and vegetables.
- Port or madeira wine
- Adds depth and sweetness to the gravy as it is added near the end.
- Soy sauce
- Adds savory depth and umami to the gravy.
The step that matters
Stew for four hours until tender. Ox-tail is rich in connective tissue that needs long, gentle, moist cooking to break down into gelatin. Stopping early leaves the meat tough, while a hard boil can toughen it and make the sauce cloudy.
