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 ↓
Boston Baked Beans
Ingredients
Directions
Prepare the beans
Soak the beans in cold water overnight, then drain.
Add fresh water and simmer the beans until soft but not broken.
Bake
Transfer the beans to a covered pan and add the diced salt pork.
Mix the salt, brown sugar, mustard, and molasses in a cup, fill the cup with boiling water, and pour over the beans.
Add enough water to nearly fill the pot.
Add more water until nearly done.
Let it cook dry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small white beans
- Form the bulk of the dish and turn tender and creamy during long cooking.
- Salt pork
- Adds fat and savory flavor that carries through the beans as they cook.
- Molasses
- Adds sweetness, dark color, and a deep caramel-like flavor to the sauce.
- Brown sugar
- Adds sweetness and helps the sauce thicken and darken as it cooks.
The step that matters
Simmer until soft but not broken. Beans cooked too hard stay firm, while overcooking splits their skins and turns them mushy. Gentle simmering softens the starch evenly so they hold their shape through baking.
Swap the beans
How well each one fits the dish's main ingredients (pork, sugar, mustard, molasses):
- Beansthe original
- Chestnutfits about as well
- Sesamefits less well
- Lentilsfits less well
Fit is the average pairing score against pork, sugar, mustard, molasses. Candidates are from the same food group and used in at least 100 recipes.
