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 ↓

Ingredients
Directions
Prepare
Mash the cold boiled haricot beans in a bowl.
Add enough breadcrumbs to make a stiff mixture.
Stir in the chopped onion, salt, and pepper.
Form the mixture into flat cakes.
Coat and fry
Dip each cake into milk, then coat with flour.
Heat oil in a pan and fry the cakes until golden brown, about 5 minutes.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Form the bulk of the cakes and provide the main body and texture.
- Breadcrumbs
- Absorb moisture and bind the mashed beans into a stiff mixture that holds its shape.
- Milk
- Helps the flour coating adhere to the cakes before frying.
- All-purpose flour
- Forms a thin dry crust that browns in the hot oil.
The step that matters
Frying the coated cakes. The oil must be hot enough to brown the flour coating quickly. If it is too cool, the cakes absorb oil and turn greasy before they turn golden.
Swap the onion
How well each one fits the dish's main ingredients (beans, pepper, milk, flour):
- Sweet potatofits better
- Capsicumfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against beans, pepper, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
