Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main savoury bulk and moisture for the filling.
- Eggs
- Set when cooked, binding the mushrooms into a soft, spoonable mixture.
- Butter
- Adds richness and helps the mushrooms brown lightly in the pan.
The step that matters
Cook over low heat until the eggs are set. High heat can toughen and curdle eggs before they set evenly. Gentle heat gives a soft, creamy texture that holds together on the toast.
Swap the parsley
How well each one fits the dish's main ingredients (mushroom, butter, pepper, egg):
- Parsleythe original
- Thymefits about as well
- Nutmegfits less well
- Tarragonfits less well
Fit is the average pairing score against mushroom, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
