Why it works: Pepper and sage match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,388 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Another Wat to Stew 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 your oven to 400°F (200°C).
Stuff the duck with pepper, salt, minced onion, and minced sage.
Roast the duck halfway.
Stew
In a pan, melt the butter and brown the flour.
Add enough weak stock or water to half cover the duck, along with more pepper and salt.
Place the duck in the pan and add the green peas.
Let it stew for 30 minutes, stirring occasionally.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main protein and rich fat that flavours the stew as it cooks.
- Butter
- Adds fat and richness, and carries flavour when it browns with the flour.
- Flour
- Browned in the butter, it thickens the stock into a gravy-like sauce.
- Green peas
- Add sweetness and soft, tender body to the stew as they cook in the liquid.
The step that matters
Brown the flour in the butter. Flour browns quickly once the butter is hot, and burnt flour turns bitter and dark. Stirring constantly and watching the colour gives a nutty flavour and lets the flour thicken the stock smoothly.
Swap the peas
How well each one fits the dish's main ingredients (pepper, onion, sage, butter, flour):

- Peasthe original
Fit is the average pairing score against pepper, onion, sage, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
