Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold duck
- Provides the main meat, which is gently reheated and browned in the butter.
- Butter
- Fat that browns the duck and ham and carries their flavor into the sauce.
- Flour
- Thickens the stock into a smooth sauce as it cooks.
- Stock
- Forms the liquid base of the sauce, adding savory flavor.
- Peas
- Provide the green vegetable centerpiece and a fresh, sweet flavor.
The step that matters
Adding the stock to the flour. Pour the stock in gradually so the flour dissolves evenly. Adding it all at once can leave lumps, so the sauce will not turn smooth and glossy.
Swap the peas
How well each one fits the dish's main ingredients (ham, butter, flour, pepper):
- Almondfits better
- Black-eyed peafits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against ham, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
