Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the dish and set firm when hard-boiled.
- Mushrooms
- Add earthy savour and a tender, moist texture when fried.
- Onions
- Add sweetness and aroma as they soften and brown in the butter.
- Butter
- Carries the frying flavour and helps the mushrooms and onions brown.
- Gravy
- Supplies liquid and savoury depth that coats the eggs and vegetables.
The step that matters
Add the sliced eggs and heat thoroughly. Hard-boiled egg whites turn rubbery and the yolks can dry out if they are overheated. Warm the eggs gently in the hot gravy just until heated through, so they stay tender.
Swap the onion
How well each one fits the dish's main ingredients (egg, mushroom, butter, pepper):
- Capsicumfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against egg, mushroom, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
