Why it works: Sage and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,388 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Roast Duck
Ingredients
Directions
Prepare the duck
If the duck is old, par-boil it in the cooker for 3 hours.
Cut the neck close.
Tie the wings and legs securely.
Stuff the duck.
Mix bread crumbs, butter, onions, sage, black pepper, and salt for the dressing.
Do not overstuff the duck.
Sew the openings firmly.
If the duck is not plump, tie a slice of salt pork over the breast.
Roast and serve
Place the duck in a casserole with the moisture mixture.
Cook in the cooker with one hot disc below and one above it.
Roast young ducks for 25–30 minutes.
Roast full-grown ducks for 1 hour or more.
Serve with currant jelly or apple sauce and green peas.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Forms the main dish; its fat renders during roasting, keeping the meat moist and browning the skin.
- Bread crumbs
- Absorb fat and juices in the dressing, giving it a soft, moist body.
- Butter
- Adds fat to the dressing, carrying flavour and keeping the crumbs moist.
- Onions
- Release moisture and sweetness as they cook inside the dressing.
- Sage
- Contributes its aromatic, savoury flavour to the dressing.
The step that matters
Do not overstuff the duck. Dressing expands as it heats and needs room; packing it tightly can leave the centre dense and undercooked while the outside overcooks.
Swap the currant
How well each one fits the dish's main ingredients (bread, butter, onion, sage, pepper, pork, vinegar):
- Lemonfits better
- Avocadofits better
- Limefits better
- Currantthe original
Fit is the average pairing score against bread, butter, onion, sage, pepper, pork, vinegar. Candidates are from the same food group and used in at least 100 recipes.
