Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
To Boil Duck
Ingredients
Directions
Prepare the ducks
Scald the ducks, then soak them in water for a few minutes.
Place the ducks in a dish and pour boiling milk over them, then let them sit for 2-3 minutes.

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 during the long gentle boiling.
- Flour
- Dredging adds a light coating that helps the surface hold onto the dish's sauce.
- Gravy
- Adds savory liquid and body to the sauce that coats the ducks.
- Onion
- Adds aromatic flavor and sweetness to the sauce as it stews.
- Butter
- Adds fat and richness to the sauce, rounding out its flavor.
The step that matters
Boiling the ducks in cold water. Starting the ducks in cold water and bringing them up to a boil lets heat penetrate gradually, so the meat cooks through and becomes tender rather than tough on the outside.
Swap the onion
How well each one fits the dish's main ingredients (milk, flour, parsley, lemon, pepper, butter):
- Shallotfits better
- Carrotfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against milk, flour, parsley, lemon, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
