Why it works: Sage and pepper 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 ↓
To Roast Ducks
Ingredients
Directions
Prepare
Cut off the legs and half of the wings of the ducks.
Stuff the legs with sage, butter, pepper, and salt.
Skewer the legs with small wire skewers.
Boil the tips of the wings, gizzard, and liver for gravy.
Roast
Baste the ducks with butter and dust them with flour.
Roast the ducks until they are a nice light brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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, whose fat renders during roasting to crisp the skin.
- Butter
- Adds richness and moisture, and helps the skin brown evenly as it cooks.
- Flour
- Dusted over the skin to help it brown and form a light crust.
- Sage
- Adds aromatic herbal flavor that perfumes the meat from inside the legs.
The step that matters
Roast the ducks until they are a nice light brown. Duck skin browns slowly as its fat renders, and the meat can dry out if it roasts too long. Watching the color rather than only the clock helps keep the meat moist while the skin crisps.
Swap the sage
How well each one fits the dish's main ingredients (butter, pepper, flour):
- Parsleyfits better
- Turmericfits about as well
- Nutmegfits about as well
- Sagethe original
Fit is the average pairing score against butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
