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 gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Soak the navy beans overnight in water.
Drain and rinse the beans, then place them in a pot.
Bake
Add the chopped onion, molasses, brown sugar, mustard, salt, and pepper.
Pour in 4 cups of water and stir to combine.
Add the pieces of salt pork on top.
Cover and bake in a 300°F (150°C) oven for 6–8 hours, checking occasionally and adding water if necessary.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the bulk and starchy body of the dish once cooked slowly until tender.
- Molasses
- Adds dark sweetness and a deep, rich flavour during the long bake.
- Brown sugar
- Adds sweetness and helps the sauce thicken and darken as it cooks.
- Salt pork
- Adds fat and savoury flavour that seasons the beans as it renders.
- Mustard
- Adds a sharp, tangy note that balances the sweetness of the molasses and sugar.
The step that matters
Covered baking with occasional water top-ups. Beans cook slowly in the liquid; if it evaporates they can dry out and scorch, while the starch and sugars gradually thicken the sauce. Checking and adding water keeps the beans submerged so they soften evenly.
Swap the onion
How well each one fits the dish's main ingredients (beans, molasses, sugar, mustard, pepper, pork):
- Capsicumfits better

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