Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Irish Stewed Duck
Ingredients
Directions
Prepare the duck
Singe, draw, and cut the ducks into 8 pieces each.
Season with salt and pepper, then fry in butter until light brown on both sides.
Brown and stew
Add the sliced onion and diced ham, browning them slightly.

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, which becomes tender as it stews in the liquid.
- Butter
- Browns the duck pieces, adding color and a rich, savory flavor to the surface.
- Flour
- Dusted on the browned pieces, it thickens the braising liquid into a light sauce.
- Beef broth
- Forms the stewing liquid that gently cooks the duck and carries the flavor.
- Port wine
- Adds sweetness and depth to the sauce as it reduces during cooking.
- Raw ham
- Adds salty, savory flavor to the stew as it browns with the onion.
The step that matters
Dredge with flour and fry again until the flour is brown. Browning the flour toasts it and builds color and nutty flavor. Stopping too early leaves a raw, pasty taste, while over-browning can turn it bitter.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, ham, flour, beef, port wine, parsley):
- Shallotfits better
- Carrotfits better
- Leekfits about as well
- Onionthe original
Fit is the average pairing score against pepper, butter, ham, flour, beef, port wine, parsley. Candidates are from the same food group and used in at least 100 recipes.
