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

Oven, in the book's wordsA medium oven

Ingredients

Directions

The book says “a medium oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the beans

  1. Pick over and wash the beans, then place them in a kettle with enough cold water to cover. Leave overnight.

  2. Drain the beans and cover them again with cold water. Boil until the skins crack when exposed to air.

  3. Put the beans in a colander and pour cold water over them.

Assemble and bake

  1. In a bean pot, place ½ pound of salt pork, cover with beans, and add another ½ pound near the surface. Top with the remaining beans.

  2. Mix the mustard, molasses, and salt, then add boiling water to cover the beans.

  3. Bake for 7 hours at 350°F (175°C).

Serve

  1. Serve with brown bread and chili sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White beans
Form the bulk of the dish and turn tender and creamy during the long bake.
Salt pork
Adds fat and savory flavor that seeps into the beans as they cook.
Molasses
Adds sweetness and a deep brown color to the sauce.
Mustard
Adds a sharp, tangy note that balances the sweetness of the molasses.

The step that matters

Boil until the skins just crack. Beans boiled past this point can split and turn mushy, while undercooked beans stay firm and tough, so the cook should check them rather than rely on a fixed time.
