Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- Provide the meat that becomes the hash, cooked first by roasting and then gently simmered.
- Cullis
- Adds a concentrated, rich body to the sauce that coats the duck pieces.
- Port wine
- Adds sweetness and depth to the sauce as it reduces when boiled.
- Shallots
- Add a mild, sweet onion flavour that builds the base of the sauce.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances the duck's fat.
The step that matters
Simmering the duck in boiling water. Duck is fatty and can turn tough or stringy if overcooked. A gentle simmer at a steady temperature keeps the meat tender while it absorbs the sauce, so the pieces stay intact rather than breaking down.
Swap the garlic
