Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Form the bulk of the dish and brown in the fat as they fry.
- Good butter
- Fat that fries the potatoes golden brown and adds rich flavour.
- Eggs
- Set into soft curds when heated, binding the dish and adding richness.
The step that matters
Leave the mixture off the heat after adding the eggs. Egg proteins set quickly when heated. If the mixture stays on the fire, the eggs overcook, turning rubbery, dry and grainy instead of soft.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg):
- Asparagusfits better
- Chivefits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
