Why it works: Parsley and pepper 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 ↓

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, cooked and finely chopped so it blends into the sauce.
- Flour
- Browned with the butter to thicken the stock into a smooth, lightly nutty sauce.
- Butter
- Adds fat and flavor, and is browned first to build a rich base.
- Port wine
- Adds sweetness and depth to the sauce, added late so its flavor stays fresh.
- Mushroom catsup
- Adds savory, umami depth to the sauce.
The step that matters
Let it stand only until heated, then serve. Holding the hash too long over heat can thicken it too far, dull the flavors, and toughen the duck. Serve as soon as it is hot through.
