Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sliced raw potatoes
- Form the bulk of the dish and brown in the hot fat, giving crisp golden edges.
- Egg
- Lightly beaten and poured over the potatoes, it sets to bind them together with a soft, moist texture.
- Chopped onion
- Softens in the fat, adding a mild, sweet aroma that flavours the potatoes.
- Pork fat or butter
- Conducts heat for frying and adds richness and flavour that helps the potatoes brown.
The step that matters
Serve immediately in a hot dish. The beaten egg continues to set as it cools, so the dish turns firm and dry if it waits. Serving it hot while the egg is still soft keeps the texture moist and tender.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, egg, pork):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against potato, pepper, egg, pork. Candidates are from the same food group and used in at least 100 recipes.
