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, whose fat renders and crisps the skin during roasting.
- Mashed potatoes
- Fill the cavity and absorb rendered juices, keeping the stuffing moist.
- Sweet fat pork
- Slices baste the birds, adding moisture and fat that promotes browning.
- Worcestershire sauce
- Adds savory depth and acidity to the gravy.
The step that matters
Baste frequently while roasting. Duck skin is thin and fatty, and frequent basting with rendered fat helps it brown and crisp evenly while keeping the meat moist. Letting the skin dry out or the fat burn can leave it leathery or bitter.
Swap the apple
How well each one fits the dish's main ingredients (potato, sage, onion, pepper, pork, sauce):
- Limefits better
- Avocadofits better
- Lemonfits better
- Applethe original
Fit is the average pairing score against potato, sage, onion, pepper, pork, sauce. Candidates are from the same food group and used in at least 100 recipes.
