Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish, becoming crisp outside and soft inside when fried.
- Butter
- Adds rich flavour and helps the potatoes brown in the pan.
- Olive oil
- Raises the frying temperature and keeps butter from burning, aiding even browning.
The step that matters
Fry potatoes on both sides until golden brown. Frying in hot fat without crowding lets the surface dry and brown through browning reactions, giving crispness and flavour. Pale, steamed potatoes lack this texture, so the pan should be hot and the slices spread out.

Fit is the average pairing score against butter, olive, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
