Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Provides the main meat, which becomes tender through parboiling and slow roasting.
- Butter
- Basting fat that helps the skin brown and keeps the surface from drying out.
- Currant jelly
- Adds sweetness and a fruity tang that balances the rich, gamey flavour of the duck.
- Browned flour
- Thickens the gravy and adds a toasted, nutty flavour.
The step that matters
Roast the duck until brown and tender, basting with butter-water and drippings.. Wild duck is lean and can dry out or toughen if overcooked. Regular basting adds moisture and fat to the surface, which helps it brown evenly while the inside stays juicy.
