Boston Baked Beans

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.

Prepare

  1. Soak the navy beans in a quart bean pot filled with water overnight.

  2. Drain the water from the soaked beans.

Bake

  1. Cover the beans with fresh water mixed with molasses.

  2. Place the pickled pork in the center, leaving ¼ inch above the beans.

  3. Bake at 300°F (150°C) for eight hours, adding 1 cup of hot water every hour except the last two.

Serve

  1. When done, serve the pork in the center of a platter with the beans around it.

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

What each ingredient does

Navy beans
Form the bulk of the dish, softening into a tender, creamy texture as they bake.
Molasses
Adds sweetness, deep brown color, and a rich, slightly bitter flavor.
Pickled pork
Contributes fat and savory, salty flavor that seasons the beans as they cook.

The step that matters

Adding hot water every hour. The beans keep absorbing liquid during the long bake. If they are allowed to dry out, they can scorch and cook unevenly, so the hourly additions keep them moist until the final hours.

Swap the beans

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

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

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