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. Soak the beans in water for 12 hours.

  2. In a pot, cover the pork with water and bring to a boil.

Bake

  1. Add the soaked beans, salt, and molasses to the pot.

  2. Bake in a slow oven at 300°F (150°C) for 6 to 8 hours, keeping the beans covered with hot water.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Beans
Provide the main body and starchy structure that softens into a creamy, tender texture.
Fat salt pork
Renders fat into the beans and adds savory richness during long, slow cooking.
Molasses
Adds sweetness, dark color, and depth of flavor through caramelization during slow baking.

The step that matters

Keep the beans covered with hot water during baking. Beans exposed to air during long baking can dry out and toughen on the surface. Keeping them submerged in hot water keeps them moist and lets them cook evenly.

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.
