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 ↓

Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the crackling and most of the fat off the pork.
Mix minced herbs, bread crumbs, salt, pepper, onion, and apple in a bowl.
Blend the mixture with the beaten eggs.
Press the mixture firmly over the meat.
Bake and serve
Bake in a brisk oven at 400°F (200°C) for twenty minutes.
Serve with tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Remains of a loin of pork
- Provides the cooked meat that the stuffing-style topping is pressed onto and served with.
- Bread crumbs
- Absorb moisture and bind the mixture so it holds together on the meat.
- Beaten eggs
- Bind the mixture and set during baking to hold the topping in place.
- Apple
- Adds moisture and mild sweetness to the topping.
The step that matters
Pressing the mixture firmly over the meat. Firm pressing helps the topping adhere to the meat and stay in one layer while it bakes. Loose packing can let it fall off or dry out unevenly in the oven.
Swap the apple
How well each one fits the dish's main ingredients (pork, bread, pepper, onion, egg):
- Avocadofits better
- Lemonfits better
- Plumfits about as well
- Applethe original
Fit is the average pairing score against pork, bread, pepper, onion, egg. Candidates are from the same food group and used in at least 100 recipes.
