Why it works: Onion and peas are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 5,460 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boast Dock
Ingredients
Directions
Prepare
Truss the ducks at the back and secure both ends with string to keep them in the seasoning.
Do not dress the ducks on the same day they are killed.
Hang them for a day or two if the weather permits.
Prepare a stuffing of Basre and onion for one duck, leaving the other unseasoned.
Cook and serve
Cook the ducks over a brisk, clear fire, basting them well throughout the cooking time.
A few minutes before serving, dredge the ducks lightly with flour to make them froth and look plump.
When the steam draws towards the fire, serve the ducks hot with brown gravy poured around them, and some in a tureen.
Serve with green peas when in season.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- The main protein; cooking over a brisk fire cooks the meat while basting keeps it moist.
- Flour
- Dredged on the surface, it helps the skin froth and brown for a plump appearance.
- Stuffing of basre and onion
- Seasons the bird from within, adding aroma and flavour to the meat.
The step that matters
Basting the ducks throughout cooking. Duck is lean and can dry out over a fierce fire; regular basting with its own juices keeps the meat moist while the skin crisps.
Swap the peas
The recipe marks peas as optional. How well each one fits the dish's main ingredients (onion, flour):
- Lentilsfits better
- Cashew nutfits better
- Black-eyed peafits better
- Peasthe original
Fit is the average pairing score against onion, flour. Candidates are from the same food group and used in at least 100 recipes.
