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 yellow soy beans for 12 hours.

  2. Place the soaked beans in a baking dish with the salt pork, onion, sugar, and mustard. Cover the mixture with cold water.

Bake

  1. Bake in a slow oven at 300°F (150°C) for at least 12 hours, adding water as needed.

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

What each ingredient does

Yellow soy beans
Form the bulk of the dish, becoming tender and creamy during long, slow cooking.
Salt pork
Adds fat and savory richness that slowly flavors the beans and cooking liquid.
Sugar
Adds sweetness and helps the beans and sauce brown during slow baking.
Onion
Contributes aromatic flavor that mellows into the sauce during baking.
Mustard
Adds a sharp, pungent note that balances the sweetness and richness.

The step that matters

Keeping the beans covered with water during the long bake. Dried beans need prolonged moist heat to soften fully. If the water evaporates, the beans can stay firm or scorch, so topping up water as needed keeps them tender and the sauce properly cooked.

Swap the onion

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

  1. Lettucefits better
  2. Welsh onionfits better
  3. Sweet potatofits better
  4. Onionthe original

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