Why it works: Onion and beans 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wholemeal bread
- Forms the bulk and structure of the pudding, soaking up the filling's moisture.
- Onions
- Add savoury sweetness and depth of flavour when fried until golden.
- Haricot beans
- Add body and a soft, starchy texture to the filling.
- Ketchup
- Adds acidity and sweetness that season the layers.
- Pastry
- Covers the filling and helps hold moisture in during boiling.
The step that matters
Fry the bread and onions separately. Frying in separate batches stops the pan from crowding, so the bread and onions brown rather than steam.
