Boston Baked Beans

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Pick, wash, and soak the beans overnight in cold water.

  2. The next day, scald the beans with baking soda and drain twice to remove the soda taste.

Bake

  1. In a red earthen jar, layer the beans and pork, ensuring the pork is covered by the beans.

  2. Dissolve molasses in hot water and pour over the beans until covered.

  3. Place in a 350°F (175°C) oven overnight, or until morning.

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

What each ingredient does

Dried beans
Provide the main body, with starch and protein that set into a tender, creamy texture.
Sweet salt pork
Adds fat and savory meaty flavor that slowly melts into the beans during baking.
Molasses
Adds sweetness, deep color, and a caramel-like flavor as it slowly cooks.
Baking soda
Raises the pH during scalding, helping bean skins soften more quickly.

The step that matters

Draining the scalded beans twice. Baking soda left on the beans leaves a soapy, bitter taste. Thorough draining and rinsing removes it before the beans are baked with sweet molasses.

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.
