Why it works: Beans and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 852 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Grind the pickled pork and onion together.
Combine the ground mixture with the boiled beans, ketchup, mustard, sugar, salt, and pepper.
Bake and serve
Place the mixture in a baking dish and add the fresh pork on top.
Bake in a slow oven at 300°F (150°C) for 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the bulk of the dish and hold the sauce as they soften during baking.
- Pickled pork
- Adds salty, savoury fat and depth of flavour to the beans.
- Ketchup
- Provides sweetness, acidity and a tomato base for the sauce.
- Sugar
- Adds sweetness and helps the sauce brown and thicken slightly in the oven.
- Mustard
- Adds sharpness that balances the sweetness of the sauce.
- Fresh pork
- Sits on top, adding meaty flavour and fat that renders into the beans.
The step that matters
Baking the beans slowly. Long, low heat lets the sauce reduce and the flavours meld while the beans become tender and the pork cooks through. Too high a heat can dry or scorch the surface before the interior is ready.
Swap the onion
How well each one fits the dish's main ingredients (beans, pork, ketchup, mustard, sugar, pepper):

- Onionthe original
Fit is the average pairing score against beans, pork, ketchup, mustard, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
