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 ↓
To Loll 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.
Boil the pork
Boil the leg of pork for about two hours until very tender.
Roast and serve
Preheat the oven to 350°F (175°C) for roasting.
Stuff the knuckle with chopped sage and onion.
Roast the leg of pork (12 pounds) for three hours.
Serve with pea pudding, savoys, or any greens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of pork
- Long moist boiling breaks down tough connective tissue, leaving the meat tender and juicy.
- Sage
- Adds a savory, herbal aroma to the meat as it roasts.
- Onion
- Adds aroma and a mild sweetness that perfumes the meat from inside the knuckle.
The step that matters
Boil until very tender. Slow, moist heat converts tough collagen in the pork into gelatin, which is what makes the meat tender. If the boil is cut short, the meat stays tough, and the long roast that follows cannot fix it.
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.
