Why it works: Beans and pork are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,000 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Boston Baked Beans

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the beans

  1. Soak the beans overnight in cold water to cover.

  2. Drain the beans in the morning.

  3. Place the beans in a pot with fresh cold water to cover.

  4. Add the pork, scored through the rind at ½‑inch intervals.

  5. Bring the mixture to a boil.

Bake

  1. Transfer the beans to a bean pot.

  2. Place 2 tablespoons of chopped salt pork at the bottom of the bean pot.

  3. Mix the salt, sugar, and molasses. Add a little boiling water. Pour the mixture over the beans.

  4. Bake in a slow oven at 300°F (150°C) for at least 8 hours.

  5. Add boiling water as necessary to keep the beans moist.

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

What each ingredient does

Beans
Provide the bulk of the dish and, once cooked slowly, a creamy, tender texture.
Molasses
Adds sweetness and deep color, and contributes to the dark browning of the baked beans.
Fat salt pork
Adds fat and savory flavor that melts into the beans during long baking.
Sugar
Adds sweetness that balances the salt and molasses and supports browning.

The step that matters

Keep the beans moist during the long bake. Beans baked for hours can dry out and scorch at the surface. Adding boiling water as needed keeps them moist, and a slow oven lets the starches soften gradually without bursting the skins.

Swap the beans

How well each one fits the dish's main ingredients (molasses, pork, sugar):

  1. Beansthe original
  2. Chestnutfits about as well
  3. Peanutfits about as well
  4. Sesamefits about as well

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