Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roast Ducks
Ingredients
Directions
Prepare the ducks
Pick, singe, draw, and remove the entrails, oil bag, crop, and pinions from the ducks.
If the ducks are old or strong, parboil them in onions and water, then discard the water.
Season the ducks with salt, pepper, butter, and flour.
Stuff and roast
Prepare the stuffing by mixing mashed potatoes, bread crumbs, sage, chopped onion, cayenne, celery seeds, parsley, and egg.
Stuff the ducks with the mixture and place them in a baking pan.
Add hot water and butter to the pan.
Roast the ducks, basting often, for about 30 minutes or until cooked through.
Dust with flour and allow to brown before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- Provide the main meat that is cooked through and browned by roasting.
- Egg
- Binds the stuffing so it holds together around the ducks.
- Irish potatoes
- Add body and moisture to the stuffing as mashed potato.
- Bread crumbs
- Soak up juices and give the stuffing a soft, cohesive texture.
- Butter
- Adds fat and richness, helping the skin brown and the meat stay moist.
The step that matters
Roast the ducks, basting often. Duck has a thick layer of fat under the skin, and basting with the pan liquid and fat keeps the meat moist while the skin crisps and browns. Cooking until fully done matters for safety, so check that the meat is cooked through rather than relying on the time alone.
Swap the onion
How well each one fits the dish's main ingredients (potato, bread, sage, pepper, celery, parsley, egg):
- Carrotfits better

Fit is the average pairing score against potato, bread, sage, pepper, celery, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
