Why it works: Ketchup and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Salmi of Duck
Ingredients
Directions
Make the stock
Break the duck bones and simmer them in 1 quart of water to make stock.
Season and heat the gravy
Season the remaining gravy with mushroom ketchup and a few drops of Worcestershire sauce.
If it is less than 1 cup, add boiling water to make up the difference.
Heat the meat and olives in the gravy, then add sherry and remove from heat.
Serve
Pile the meat in the center of a small platter, pour the gravy over it, and garnish with triangles of toasted bread and tufts of parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover roasted duck meat
- Forms the main body of the dish and carries the savory flavor.
- Duck bones
- Simmered in water, they release gelatin that gives the stock body and mouthfeel.
- Mushroom ketchup
- Adds concentrated savory, umami depth to the gravy.
- Olives
- Contribute briny, salty bite that cuts through the richness of the duck.
- Sherry
- Adds acidity and aroma that brighten the gravy.
The step that matters
Add the sherry and remove from heat. Sherry's aromatic compounds are volatile and fade with prolonged heating, so it should be stirred in at the end, off the heat. Keeping the meat and gravy from boiling also prevents the duck from toughening.
Swap the parsley
How well each one fits the dish's main ingredients (meat, mushroom, ketchup, sauce, olive, sherry, bread):
- Thymefits better
- Capersfits better
- Garlicfits about as well
- Parsleythe original
Fit is the average pairing score against meat, mushroom, ketchup, sauce, olive, sherry, bread. Candidates are from the same food group and used in at least 100 recipes.
