Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. 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 the base
Melt the drippings in a pan.
Add flour and stir until well blended.
Mash the beans and potatoes through a potato ricer.
Shape and bake
Combine all ingredients and shape into a loaf.
Place a strip or two of bacon on top.
Bake at 350°F (175°C) until well blended.
Serve with or without tomato sauce, onions, cauliflower, or cabbage.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Adds body and softness, helping the loaf hold together while staying moist.
- Cooked beans or peas
- Form the bulk of the loaf and provide its main texture and protein.
- Thick cream sauce
- Adds moisture and richness so the loaf does not dry out during baking.
- Flour
- Thickens the drippings into a binder that helps the loaf set and hold its shape.
The step that matters
Mash the beans and potatoes through a potato ricer. Pushing the cooked beans and potatoes through a ricer gives a fine, even texture. Coarse lumps can leave the loaf crumbly and uneven when it sets.
Swap the onion
