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 is roasted whole and trussed for even cooking.
- Bread crumbs
- Absorb the butter and onion juices to form a moist, soft stuffing.
- Butter
- Adds fat and richness to the stuffing, carrying flavor and moisture.
- Grated onion
- Adds savory aroma and moisture to the stuffing as it cooks.
- Drippings from the ducks
- Add rendered fat and savory flavor, helping the duck brown while it roasts.
The step that matters
Pour off most of the fat from the pan. Duck releases a lot of fat as it roasts. Leaving too much in the pan makes the gravy greasy and can dilute its flavor, so most of it should be removed before thickening.
Swap the onion
How well each one fits the dish's main ingredients (bread, butter, pepper, sage):
- Capsicumfits better
- Shallotfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against bread, butter, pepper, sage. Candidates are from the same food group and used in at least 100 recipes.
