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 ↓

Ingredients
Directions
The book says “a good oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Soak the beans overnight.
In the morning, cover them with boiling water and let them sit until swollen and soft.
Place the beans in a deep baking dish, score the salt pork, and push it into the beans.
Bake
Add salt, mustard, molasses, and enough hot water to cover the beans.
Cover the dish and bake in a slow oven (300°F / 150°C) for six hours, checking occasionally to add more water if needed.
For the last half-hour, bake uncovered at a higher temperature.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Provides the bulk of the dish, softening during long baking into a tender, creamy texture.
- Salt pork
- Renders fat and savory flavor into the beans, enriching their taste and mouthfeel.
- Molasses
- Adds sweetness and deep brown color as it caramelises slowly in the oven.
- Prepared mustard
- Adds a sharp note that balances the sweetness of the molasses.
The step that matters
Keeping the beans covered with liquid during the long bake. Beans absorb water as they cook, and if they are left exposed they can dry out and scorch. Slow, covered heat lets the starches soften evenly, so topping up the water keeps the beans tender and creamy.
