Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and starch that hold the croquettes together in shape.
- Butter
- Adds fat that enriches flavour and keeps the mash soft and moist.
- Egg
- Binds the mashed potato and helps the bread crumbs stick to the shapes.
- Bread crumbs
- Form a crisp, browning outer coating during frying.
The step that matters
Fry in hot oil until golden brown. Oil that is hot enough sets and browns the crumb coating quickly, so the crust crisps before the inside absorbs excess oil and turns greasy.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, pepper, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against butter, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
