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 a Leg of Pork
Ingredients
Directions
Prepare
Score the skin of the pork leg in narrow stripes, forming diamonds if desired, and rub in powdered sage.
Lift the skin at the knuckle and stuff it 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 with the filling, pressing it in firmly.
Roast
Brush the skin with sweet oil to make it crisp and brown.
Position the spit away from the fire to prevent burning the skin.
Roast the leg 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.
Serve
Skim the fat from the gravy and thicken it with a little flour.
Serve the roast leg of pork 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
- Pork leg
- Forms the main meat, which becomes tender and juicy during long slow roasting.
- Bread crumbs
- Absorb the juices and onion flavour in the stuffing, giving it body and moisture.
- Beaten egg yolk
- Binds the stuffing together so it holds its shape when sliced.
- Sweet oil or fresh butter
- Fat brushed on the skin that promotes crisping and browning.
- Flour
- Thickens the drippings into a smooth gravy.
The step that matters
Position the spit away from the fire. Direct heat burns the skin before the thick meat cooks through. Gentle, indirect heat over a long roast lets the interior become tender while the skin slowly crisps.
Swap the onion
How well each one fits the dish's main ingredients (pork, sage, bread, pepper, egg, butter, flour):
