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 mixture

  1. Pass the cooked beans through a ricer.

  2. Mix in the bread crumbs or cooked cereal, chopped onion, fat, salt, and pepper.

  3. Moisten the mixture with white sauce, gravy, or tomato sauce.

Bake and serve

  1. Transfer the mixture to a greased deep bread tin.

  2. Bake in a moderate oven at 350°F (175°C) for 1 hour.

  3. Serve hot with additional tomato sauce.

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

What each ingredient does

Cooked beans
Form the bulk and body of the loaf once mashed through a ricer.
Bread crumbs
Absorb liquid and help bind the mashed beans together.
Cooked cereal
Absorbs moisture and helps the loaf hold its shape.
Fat
Adds richness and keeps the loaf from drying out.
Chopped onion
Adds savoury flavour and aroma as the loaf bakes.
White sauce, gravy, or tomato sauce
Adds moisture so the loaf stays tender rather than dry.

The step that matters

Moisten the mixture. The mashed beans and crumbs need enough liquid to bind and hold together. Too dry, the loaf crumbles when sliced; too wet, it stays soft and slumps in the tin.

Swap the onion

How well each one fits the dish's main ingredients (beans, bread, pepper, sauce):

  3. Spinachfits better
  4. Onionthe original

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