Name: A Leg of Pork Roasted
Ingredients: 1 young dairy-fed leg of pork; fresh butter; sage, scalded and chopped fine; 1 onion, parboiled and chopped; bread crumbs; 1 small apple, chopped fine; pepper; coarse sea salt

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 ↓

A Leg of Pork Roasted

Ingredients

Directions

Prepare

Score the skin of the leg of pork with a sharp knife.
Rub a little fresh butter over the skin to help it brown and crisp.
Mix the chopped sage, parboiled onion, bread crumbs, and chopped apple in a bowl and season the mixture with pepper and coarse sea salt.

Stuff and roast

Make an incision to separate the skin from the fat at the under and fillet end of the leg.
Stuff the mixture into the incision.
Roast the leg of pork until fully cooked; timing will depend on the size.
Serve with apple sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Pork leg: Provides the main meat, which becomes tender and fully cooked during roasting.
Fresh butter: Fat on the skin that helps it brown and crisp in the oven.
Bread crumbs: Absorb juices and moisture from the apple and onion, giving the stuffing body.
Onion: Adds savory flavor and moisture to the stuffing.
Apple: Adds natural sweetness that balances the savory sage and pork.

The step that matters

Roast until fully cooked. A large cut of pork needs enough time for heat to reach the center. Size varies, so the record gives no fixed time; rely on the thickest part reaching a safe internal temperature rather than on the clock alone.

Swap the apple
