Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts with the flour to form a base that thickens the mixture and adds richness.
- Flour
- Thickens the butter and the juices from the tomatoes and mushrooms into a body.
- Tomatoes
- Add moisture and acidity that give the filling its fresh, tangy flavour.
- Mushrooms
- Add earthy flavour and moisture to the filling.
- Veal, tongue, or chicken
- Adds savoury meat flavour and some protein to the filling.
- Eggs
- Set when heated, binding the filling together and giving the omelet its structure.
The step that matters
Break in the eggs and season with salt and cayenne pepper. Eggs set with heat, so they should be added once the filling is hot and cooked through, then left just long enough to set. Overcooking makes them tough and dry, and seasoning lightly and evenly keeps the flavour balanced.
