Why it works: Beans and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 5,242 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bean Loaf
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Chop the onions and green pepper finely.
Make and bake the loaf
In a bowl, mix together the cooked navy beans, chopped onions, chopped green pepper, beaten eggs, bread crumbs, drippings, sweet milk, salt, and cayenne pepper.
Mold the mixture into a loaf shape.
Bake in the preheated oven until heated through.
Serve
Serve hot, plain or with tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the bulk and body of the loaf, setting its texture.
- Eggs
- Bind the mixture so the loaf holds its shape when baked.
- Bread crumbs
- Absorb moisture and help the loaf hold together with a softer texture.
- Sweet milk
- Adds moisture so the loaf stays tender rather than dry.
- Drippings
- Add fat for richer flavor and a more tender crumb.
The step that matters
Mold the mixture into a loaf shape. The mixture is soft and held together only by beaten egg and crumbs, so it should be packed firmly and evenly. Loose packing can crumble or bake unevenly.
Swap the onion
How well each one fits the dish's main ingredients (beans, egg, bread, pepper, milk):
- Capsicumfits better
- Asparagusfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against beans, egg, bread, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
