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 the beans

  1. Soak the beans overnight.

  2. Par-boil the beans in the morning and drain all the water.

Bake

  1. Place the beans in a bean jar and press the piece of pickled pork into the top.

  2. Add the molasses and salt.

  3. Bake slowly at 300°F (150°C) for 16 to 18 hours, adding boiling water as needed.

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 soften into a tender, creamy texture during slow baking.
Pickled pork
Adds savory fat and salty, smoky flavor that seeps into the beans as they bake.
Molasses
Adds sweetness, dark color and depth, and its sugars deepen in color during long baking.

The step that matters

Adding boiling water as needed during the long bake. Over many hours the liquid evaporates, and beans left exposed can dry out, scorch, or cook unevenly. Keeping them moist lets the starches soften fully and the sauce stay saucy rather than dry or burnt.

Swap the beans

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

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

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