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. Soak the beans overnight in cold water.

  2. In the morning, drain and parboil the beans with a pinch of baking soda until tender.

  3. Rinse the beans and place them in an earthen bean pot.

Bake

  1. Add the pork with the rind side up on top of the beans.

  2. Bake in a 350°F (175°C) oven for about 7 hours, keeping the water level with the top of the beans.

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

What each ingredient does

Navy beans
Provide the main body of the dish, becoming tender and creamy during the long bake.
Salt pork
Adds fat and savory flavor that seeps into the beans, and its rind crisps on top.
Molasses
Adds sweetness and dark color, deepening the flavor of the beans as they bake.
Dry mustard
Adds a sharp, pungent note that balances the sweetness of the molasses.

The step that matters

Keeping the water level with the top of the beans. Beans exposed to air during a long bake can dry out and toughen on top. Keeping them submerged lets them cook evenly and soften through.
