Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelette as they cook, forming its body.
- Butter
- Adds richness and helps keep the eggs from sticking to the hot pan.
The step that matters
Cook until set, then fold and serve. Eggs cook quickly and turn rubbery if overheated. Removing the omelette once the surface is just set keeps it tender and moist inside.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, ham):
- Parsleythe original
- Nutmegfits about as well
- Capersfits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, butter, ham. Candidates are from the same food group and used in at least 100 recipes.
