Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Roast Duck
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the duck
Preheat the oven to 400°F (200°C).
Rub the duck with salt, pepper, and garlic or onion.
Roast
Brown the duck quickly in the oven.
After browning, add ½ cup of water and baste the duck well.
Cook for 45 minutes, ensuring the oven temperature is correct.
To check doneness, insert a fork into the thickest part of the breast; clear juice should run out.
Remove the duck from the oven immediately.
Make the gravy and serve
For gravy, combine the pan juices with tomatoes, Worcestershire sauce, sugar, and Tabasco sauce.
Keep about 1 cup of the juice to pour over the duck when serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the meat and fat that the dish is built around, cooking down as it roasts.
- Garlic or onion
- Rubbed into the bird to add aromatic flavour to the meat.
- Tomatoes
- Add acidity and body to the pan juices, forming the base of the gravy.
- Sugar
- Balances the acidity of the tomatoes and helps the gravy brown slightly.
- Worcestershire sauce
- Adds savoury depth and tang to the gravy.
The step that matters
Check doneness at the thickest part of the breast. Poultry must be fully cooked through, and the thickest part is the slowest to heat. Clear juice, not pink, shows the meat has reached a safe, done state, so judging by time alone can leave it underdone or dry.
Swap the clove
How well each one fits the dish's main ingredients (mallard duck, pepper, tomato, sauce, sugar):
- Corianderfits better
- Celeryfits better
- Thymefits better
- Clovethe original
Fit is the average pairing score against mallard duck, pepper, tomato, sauce, sugar. Candidates are from the same food group and used in at least 100 recipes.
