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
Prepare the beans
Soak the pea beans in cold water overnight.
Drain the beans.
Simmer them in fresh cold water until soft enough to pierce with a pin, being careful not to boil them.
If desired, boil the onion with the beans.
Drain the beans in a colander and rinse with cold water.
Assemble and bake
Place the beans and onion in a bean pot.
Scrape the rind of the salt pork until white and cut it into half-inch strips.
Bury the pork in the beans, leaving only the rind exposed.
Mix the salt, mustard, and molasses in a bowl.
Fill the cup with hot water and pour it over the beans.
Add enough more water to cover the beans.
Cover and bake for eight hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pea beans
- Form the bulk of the dish, becoming tender and creamy during the long, slow cooking.
- Salt pork
- Adds fat and savory flavor that slowly seasons the beans, with the rind left exposed to crisp.
- Molasses
- Adds sweetness and deep color, and helps the sauce thicken and darken as it bakes.
- Mustard
- Adds a sharp, pungent note that balances the sweetness of the molasses.
The step that matters
Simmer without boiling. Beans cooked at a hard boil can break apart and split their skins, while gentle simmering keeps them whole and evenly tender for the long bake.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beans, pork, mustard, molasses):
- Lettucefits better
- Welsh onionfits better
- Broccolifits better
- Onionthe original
Fit is the average pairing score against beans, pork, mustard, molasses. Candidates are from the same food group and used in at least 100 recipes.
