Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Roasting Pork
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Score the skin of the pork leg in narrow stripes, about ¼ inch apart.
Stuff the knuckle with sage and onion.
Roast
Roast in a 400°F (200°C) oven for about 3 hours, ensuring it is thoroughly cooked.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 as it cooks through.
- Sage
- Adds a savory, aromatic herbal flavor to the stuffing.
- Onion
- Adds savory sweetness and moisture to the stuffing as it cooks.
The step that matters
Roast until thoroughly cooked. Pork must reach a fully cooked internal temperature to be safe to eat. Cooking time alone is not a reliable guide, so the meat should be checked with a thermometer in its thickest part.
Swap the sage
How well each one fits the dish's main ingredients (pork, onion):
- Garlicfits better
- Thymefits better
- Cuminfits about as well
- Sagethe original
Fit is the average pairing score against pork, onion. Candidates are from the same food group and used in at least 100 recipes.
