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 the pork
Score the skin of the leg of pork in narrow stripes. Form diamonds if desired.
Rub powdered sage into the skin.
Lift the skin at the knuckles.
Stuff the skin with minced onion, sage, pepper, salt, and beaten egg yolk.
Fasten the skin down with buttered string or skewers.
Make deep incisions in the large end of the leg.
Stuff the incisions with the filling. Press the filling in firmly.
Roast and finish
Rub olive oil all over the skin with a brush to make it crisp and brown.
Position the leg of pork away from the fire to prevent burning and blistering of the skin.
Roast the leg for 3 to 4 hours, basting it frequently with sweet oil or its own drippings.
Skim the fat from the gravy and thicken it with a little flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of pork
- Forms the main body of the dish, becoming tender and juicy as it roasts slowly.
- Olive oil
- Coats the skin to help it crisp and brown in the oven.
- Beaten egg yolk
- Binds the onion and sage filling so it holds together inside the pork.
- Flour
- Thickens the drippings into a smooth gravy.
- Minced onion
- Adds savory flavor to the stuffing as it cooks inside the meat.
The step that matters
Position the leg away from the fire. Direct, intense heat can burn and blister the skin before the interior cooks through. Keeping the leg farther from the heat source allows gentle, even roasting and a crisp, browned skin.
Swap the onion
How well each one fits the dish's main ingredients (pork, sage, pepper, egg, olive, flour):
- Capsicumfits better
- Spinachfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against pork, sage, pepper, egg, olive, flour. Candidates are from the same food group and used in at least 100 recipes.
