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 ↓
Roast Leg of Pork
Ingredients
Directions
Prepare the leg
Make narrow strips in the skin and rub in powdered sage.
Lift the skin at the knuckle and stuff with minced onion, sage, bread crumbs, pepper, salt, and beaten egg yolk.
Fasten the skin down with a buttered string or skewers.
Make deep incisions in the large end of the leg and stuff them, pressing the filling in tightly.
Roast
Brush the skin with sweet oil or fresh butter to achieve a crisp, brown finish.
Roast the leg of pork for 3 to 4 hours, brushing it regularly with sweet oil or fresh butter.
Avoid basting with its own drippings to keep the skin tender.
Gravy and serving
Skim the fat from the gravy and thicken it with a little flour.
Serve with apple sauce, mashed potatoes, and mashed turnips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of pork
- Main meat; its fat and connective tissue become tender and juicy during long roasting.
- Bread crumbs
- Absorb moisture in the stuffing, giving it body so it holds together when roasted.
- Egg yolk
- Binds the stuffing so it holds together as it cooks.
- Sweet oil or fresh butter
- Fat that carries heat to the skin, helping it brown and crisp.
- Flour
- Starch that thickens the drippings into a smooth gravy.
- Minced onion
- Adds savoury aroma and moisture to the stuffing.
The step that matters
Brushing the skin with fat, not drippings. Brushing the skin with oil or butter helps it brown and crisp. Basting with the pork's own juices adds moisture to the skin's surface, which slows crisping and keeps it soft.
Swap the onion
How well each one fits the dish's main ingredients (pork, sage, bread, pepper, egg, butter, flour):
- Capsicumfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against pork, sage, bread, pepper, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
