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 ↓
Butter Beans Rissoles
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Soak the butter beans in butter overnight.
Fry the chopped onions in the butter until soft.
Boil the soaked beans in enough water until tender.
Mash the beans or pass them through a nut mill.
Mix the mashed beans with fried onions, mashed potatoes, herbs, and seasoning.
Shape and bake
Form the mixture into small rissoles and roll them in breadcrumbs.
Place the rissoles on a buttered baking tray and dot with a few bits of butter.
Bake in a 400°F (200°C) oven until golden brown.
Serve with vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter beans
- Provide the main bulk and soft, creamy body of the rissoles once mashed.
- Mashed potatoes
- Add starch that helps the mashed mixture hold together when shaped.
- Onions
- Add sweetness and savoury aroma as they soften in butter.
- Butter
- Adds richness and fat, and helps the outside brown in the oven.
- Breadcrumbs
- Form a crisp, golden coating on the outside of each rissole.
The step that matters
Boil the beans until fully tender. Beans must be cooked until completely soft before mashing. Undercooked beans stay firm and grainy, so the rissoles will not bind smoothly or taste creamy.
Swap the beans
How well each one fits the dish's main ingredients (butter, potato, onion):
- Sesamefits about as well
- Beansthe original
- Peanutfits about as well
- Chickpeafits less well
Fit is the average pairing score against butter, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
