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 ↓
Pork, Leg Of, Roasted
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the leg
Remove the bones down to the knuckle bone and break them into smaller pieces.
Simmer the broken bones for gravy.
Prepare the forcemeat as directed, press it lightly inside the leg, and secure the opening.
Score the skin in narrow strips and brush with salad oil.
Roast and serve
Roast it before a clear fire or bake it in a moderate oven at 350°F (175°C).
Serve the gravy and apple sauce in sauceboats.

Onion and sauce barely smell alike, yet cooks put them together in 10,474 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork leg
- Forms the main joint of meat that is roasted and carved.
- Onion forcemeat
- Stuffing that fills the cavity, adding moisture and flavour as it cooks inside the leg.
- Salad oil
- Brushed on the scored skin to help it brown and crisp in the oven.
- Gravy
- Made from simmered bones, it adds savoury richness and moisture to the meat.
The step that matters
Scoring and oiling the skin. Narrow scores let fat render and heat reach the skin, while oil promotes even browning. Skipping either can leave the skin soft and pale rather than crisp.
Swap the apple
How well each one fits the dish's main ingredients (pork, onion, sauce):
- Avocadofits better
- Coconutfits about as well
- Mangofits about as well
- Applethe original
Fit is the average pairing score against pork, onion, sauce. Candidates are from the same food group and used in at least 100 recipes.
