Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites beaten separately add lift and a light, airy structure, while yolks enrich the set.
- Prawns
- Provide the main protein and a firm, sweet bite that holds its shape in the omelette.
- Potatoes
- Add body and a soft, filling texture to the omelette.
- Tomatoes
- Contribute moisture and gentle acidity that brightens the onion base.
- Onions
- Build a sweet, savoury base through slow softening in butter.
The step that matters
Fold the whites and yolks together. Beaten egg whites trap air that gives lift; folding gently rather than stirring keeps that air from collapsing, so the omelette stays light.

Fit is the average pairing score against butter, tomato, pepper, potato, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
