Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
An Omelette
Ingredients
Directions
Prepare the filling
Beat the eggs for a few minutes.
Add chopped parsley and stewed, chopped mushrooms to the eggs.
Cook
Heat the butter in a pan until sufficiently hot.
Pour the egg mixture into the pan and fry until golden brown, being careful not to overcook.
Optionally, hold a salamander over the surface for a minute to remove the raw appearance, or fold the omelette over.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a tender structure when cooked, forming the body of the omelette.
- Butter
- Conducts heat into the eggs and adds richness and browning to the surface.
- Mushrooms
- Add savory bulk and moisture to the filling; stewing first releases excess water.
The step that matters
Pour the egg mixture into the pan and fry until golden brown, being careful not to overcook.. Eggs turn firm and rubbery when proteins tighten under too much heat. Removing the pan at the right moment keeps the omelette tender while the surface still browns.
Swap the parsley
How well each one fits the dish's main ingredients (egg, mushroom, butter):
- Parsleythe original
- Thymefits about as well
- Nutmegfits about as well
- Capersfits less well
Fit is the average pairing score against egg, mushroom, butter. Candidates are from the same food group and used in at least 100 recipes.
