Why it works: Sage and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,485 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Duck, Stewed Whole
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Roast and stew
Roast the duck in a 400°F (200°C) oven for 20 minutes.
Place the duck in a stewpan with the herbs and onions.
Cook slowly for 1 hour.
Make the sauce
Melt the butter in a pan, add the flour, and cook until browned.
Strain in the brown stock and stir over heat until smooth.
Remove from heat and simmer gently for 20 minutes, then strain the sauce.
Serve
Serve the duck on a hot dish, pour some sauce over it, and serve the remainder in a sauceboat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat, which becomes tender through slow cooking with moisture.
- Butter
- Carries flavour and enriches the sauce while it cooks with the flour.
- Flour
- Thickens the sauce when cooked with butter to form a roux.
- Brown stock
- Forms the liquid base of the sauce, adding savoury depth and body.
- Onions
- Add sweetness and aromatic flavour as they soften during the slow cooking.
The step that matters
Making the roux. Cooking the flour in butter until browned removes raw starch taste and builds colour and nutty flavour; if it is undercooked or burnt, the sauce tastes pasty or bitter and thickens unevenly.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, sage, parsley, thyme, pepper):

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