Why it works: Beans and peanut match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 190 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Bean Loaf
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the loaf
In a bowl, combine the cooked beans, beaten egg, peanut butter, milk, sage, and chopped onion.
Mix in enough bread crumbs to thicken the mixture.
Season with pepper to taste.
Transfer the mixture to a baking dish and bake until firm enough to slice when cold.

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 of the loaf and provide its main body and substance.
- Egg
- Binds the mixture so it sets firm as it bakes.
- Bread crumbs
- Absorb moisture and thicken the mixture so it holds its shape.
- Peanut butter
- Adds fat and richness, giving a softer, creamier texture.
- Milk
- Adds moisture and loosens the mixture before it sets.
The step that matters
Bake until firm enough to slice when cold. The egg sets as it heats, but the loaf firms further as it cools. Slicing too early can crumble it, so let it cool fully before cutting.
Swap the sage
How well each one fits the dish's main ingredients (beans, egg, peanut, butter, milk, onion, bread):
- Garlicfits better
- Cinnamonfits better
- Nutmegfits better
- Sagethe original
Fit is the average pairing score against beans, egg, peanut, butter, milk, onion, bread. Candidates are from the same food group and used in at least 100 recipes.
