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 as they cook, forming the body of the omelette.
- Milk
- Adds moisture and tenderness, keeping the cooked eggs softer and less dense.
- Lard or butter
- Coats the pan to limit sticking and adds richness to the flavour.
The step that matters
Stirring the egg mixture in the pan. Stirring occasionally keeps the egg proteins moving so small curds form and the mixture does not stick or scorch on the hot surface. Leaving it still can create a rubbery, browned bottom before the top sets.
Swap the onion
How well each one fits the dish's main ingredients (egg, pepper, milk, butter):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, pepper, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
