Why it works: Sage and lemon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 887 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
To Roast Ducks
Ingredients
Directions
The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare the ducks
Draw the ducks and stuff them with the shredded onion, sage leaves, salt, and pepper.
Spit the ducks and dust them with flour.
Roast
Baste the ducks with lard and roast them in a very hot oven (400°F / 200°C) for about 20 minutes.
Just before removing them from the spit, dust them with flour and baste again.
Make the gravy and serve
Prepare gravy using the gizzards and pinions, mace, peppercorns, catsup, and lemon pickle; strain it.
Pour the gravy over the ducks and serve with onion sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lard
- Fat that bastes the skin, helping it brown and crisp in the hot oven.
- Flour
- Dusted on the surface, it helps the skin brown and crisp during roasting.
- Onion
- Stuffed inside the birds, it adds aroma that gently scents the meat as it cooks.
The step that matters
Roasting in a very hot oven. High heat renders the duck's fat and crisps the skin, while regular basting keeps the surface from drying out. Too little heat leaves the skin flabby and greasy.
Swap the mace
How well each one fits the dish's main ingredients (onion, sage, pepper, flour, lemon):
- Marjoramfits better
- Thymefits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against onion, sage, pepper, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
