Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Boil the white beans in water for 4 hours, then drain.

  2. Place the beans in a bean jar.

Season and bake

  1. Add salt, molasses, ground chili, and chopped onion.

  2. Lay slices of salt pork on top of the beans.

  3. Add enough water to cover the beans.

  4. Bake in a 300°F (150°C) oven for 5 hours.

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

What each ingredient does

White beans
Form the bulk of the dish and become tender during the long cooking.
Cooking molasses
Adds sweetness and a deep color as it caramelizes slowly in the oven.
Salt pork
Adds fat and savory flavor that seeps down into the beans as they bake.
Onion
Adds aromatic sweetness and savory depth to the cooking liquid.

The step that matters

Add enough water to cover the beans. Beans that poke above the liquid dry out and toughen during the long bake. Keeping them submerged lets them soften evenly and absorb the seasoning.

Swap the onion

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

  1. Potatofits better
  2. Mustardfits better
  3. Sweet potatofits better
  4. Onionthe original

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