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. Preheat oven to 300°F (150°C).

  2. Cook the soaked beans in water for 30 minutes.

Bake

  1. In a baking pot, combine the beans, molasses, mustard, salt, pepper, and salt pork.

  2. Cover and bake for 6 hours.

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

What each ingredient does

Dried beans
Form the bulk of the dish and become tender during the long, slow bake.
New orleans molasses
Adds sweetness, deep color, and a rich flavor to the beans.
Salt pork
Adds fat and savory flavor that seasons the beans as they bake.
Ground mustard
Adds a sharp, pungent note that balances the sweetness of the molasses.

The step that matters

Cover and bake slowly. Long, gentle heat lets the beans soften fully and the starches gelatinize, while the covered pot keeps moisture from evaporating too fast. Too much heat or too little liquid can leave beans firm or dry.
