Why it works: Apple and sage work together. They rank in the top 10% of all ingredient pairs, and cooks put them together in 755 recipes. Both carry 2-hexenal, which smells green, leafy. The science ↓
Roast Duck
Ingredients
Directions
Prepare and roast
Dress and stuff the duck as you would other fowls.
If the duck is old, parboil it before roasting.
Roast young ducks for 25 to 30 minutes, and full-grown ducks for 1 hour or more, basting frequently.
Serve
Serve with currant jelly, apple sauce, and green peas.
Use leftovers
For leftovers, place the remains in a stew pan with 2 cups of gravy and a little sage.
Cover and simmer for 30 minutes, then add 2 cups of boiled green peas.
Stew for a few minutes, then serve with the gravy and peas.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat, which becomes tender and browned as it roasts.
- Currant jelly
- Adds sweet-tart acidity that cuts through the rich duck fat.
- Apple sauce
- Adds moisture and mild sweetness that balance the rich, fatty meat.
- Gravy
- Adds moisture and savoury flavour to the duck and leftovers.
The step that matters
Roasting time by duck age. Young and full-grown ducks need very different roasting times. Undercooking leaves the meat unsafe, while overcooking dries it out. Basting keeps the surface moist and helps it brown evenly.
Swap the currant
How well each one fits the dish's main ingredients (apple, sauce, peas, sage):
- Lemonfits better
- Plumfits better
- Pearfits better
- Currantthe original
Fit is the average pairing score against apple, sauce, peas, sage. Candidates are from the same food group and used in at least 100 recipes.
