Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a soft structure that holds the dish together when cooked.
- Red herring
- Supplies the main flavour and savoury body of the dish.
- Butter or salad oil
- Fat for the pan that keeps the egg mixture from sticking and adds richness.
The step that matters
Cook until the eggs are set. Eggs cooked over heat turn from liquid to firm as their proteins coagulate. Removing them too early leaves them runny, while overcooking makes them dry and rubbery.
Swap the onion
How well each one fits the dish's main ingredients (egg, pepper, parsley, butter, lemon):
- Shallotfits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, pepper, parsley, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
