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 ↓
Fried Potatoes with Eggs
Ingredients
Directions
Prepare
Slice the cold boiled potatoes.
Fry the potatoes in good butter until brown.
Beat 1 or 2 eggs in a bowl.
Finish and serve
Stir the eggs into the potatoes just before serving.
Do not leave the mixture on the fire after adding the eggs to prevent them from hardening.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled potatoes
- Provide the main body of the dish; cold potatoes hold their shape better when sliced and fried.
- Good butter
- Fat that carries the frying heat and gives the potatoes a golden-brown surface and rich flavour.
- Eggs
- Set with gentle heat to bind the potato slices together into a tender, cohesive mixture.
The step that matters
Stop the heat once the eggs go in. Egg proteins set and toughen when overheated, so leaving the mixture on the fire after adding the eggs can make them hard and rubbery 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.
