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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make a small cut in the knuckle of the pork leg and fill it with sage, onion, pepper, and salt.
Roast and score
Roast the pork until half done, then score the skin in a crisscross pattern without cutting deeper than the outer rind.
Remove excess fat from the roasting pan.
Make the gravy and serve
Stir flour with a little water and add it to the pan, then add more water to achieve the desired consistency.
Serve the gravy in a gravy boat alongside the pork.

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 juicy during slow roasting.
- Flour
- Thickens the pan juices into a smooth gravy as it heats.
- Sage
- Adds a savory, aromatic herb flavor that penetrates the meat from the stuffed knuckle cut.
- Onion
- Adds aromatic sweetness and moisture as it cooks inside the pork.
The step that matters
Scoring the skin without cutting into the meat. Cutting deeper than the outer rind exposes the lean meat, which can dry out during roasting. A shallow score lets fat render and helps the skin crisp.
Swap the onion
How well each one fits the dish's main ingredients (pork, sage, pepper, flour):
- Capsicumfits better
- Turnipfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against pork, sage, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
