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 ↓
Baked Pork and Beans
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 beans
Soak the pea beans in cold water overnight.
Drain the beans and simmer them in fresh cold water until soft enough to pierce with a pin, about 1–2 hours.
If desired, add the onion while simmering.
Prepare the pork and dish
Drain the beans and place them in a bean pot with the onion.
Pour boiling water over the salt pork, scrape the rind until white, and cut it into half‑inch strips.
Bury the pork in the beans, leaving the rind exposed.
Mix the salt, mustard, and molasses with hot water.
Pour the mixture over the beans.
Add enough water to cover the beans, keeping them covered until the last hour.
Bake
During the last hour, lift the pork to the surface to crisp.
Bake for 8 hours at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pea beans
- Provide the bulk of the dish, softening during simmering and long baking into a tender texture.
- Salt pork
- Adds fat and savory flavor as it renders into the beans, and its rind crisps on top.
- Molasses
- Adds sweetness and dark color, and helps the sauce thicken and brown during long baking.
- Mustard
- Adds a sharp, pungent note that balances the sweetness of the molasses.
The step that matters
Keeping the beans covered until the last hour. Covering the beans keeps them moist during the long bake so they do not dry out or scorch, while the uncovered final hour lets the pork crisp and the sauce thicken.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beans, pork, mustard, molasses, butter):
- Lettucefits better
- Potatofits better
- Welsh onionfits better
- Onionthe original
Fit is the average pairing score against beans, pork, mustard, molasses, butter. Candidates are from the same food group and used in at least 100 recipes.
