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
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 beans in water overnight, then cover with fresh water.
In the morning, boil the beans until easily crushed but still intact.
Drain the beans and place them in an earthen pot.
Season and bake
Add salt, molasses, mustard, and baking soda to the pot.
Score the salt pork and place it on top of the beans.
Bake uncovered in a 350°F (175°C) oven all day, keeping the beans moist.
At night, remove the pork, cover the pot, and bake overnight with the fire checked.
Reheat the pork in the morning and serve on top of the beans.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White pea beans
- Form the main body of the dish, becoming tender and creamy as they cook slowly.
- Molasses
- Adds sweetness and dark color, and helps the beans brown during long baking.
- Salt pork
- Releases fat and flavor into the beans as it bakes, adding richness.
- Baking soda
- Raises the pot's alkalinity, which helps the bean skins soften during cooking.
The step that matters
Keeping the beans moist during the all-day bake. Beans dry out and toughen if the liquid evaporates during long uncovered baking. Keeping them moist lets the starches soften fully and the flavors blend.
