Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main body of the dish, becoming tender as they stew gently in the gravy.
- Rich beef gravy
- Provides the liquid base and savoury depth that the eels cook in.
- Anchovies
- Add concentrated salty, savoury flavour that deepens the gravy.
- Port wine
- Adds sweetness and fruity richness to the sauce.
- Made mustard
- Adds sharpness that balances the richness of the gravy.
The step that matters
Covering the pan and stewing gently. Eels are delicate and can toughen or break apart if overcooked or boiled hard. Gentle, covered stewing keeps the flesh tender and moist while the flavours meld.
