Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Soften slowly in stock to form the body and flavour of the base.
- Butter
- Adds richness and a smooth, silky texture to the pressed mushroom mixture.
- Onion
- Contributes aromatic sweetness and savoury depth to the base.
- Poached eggs
- Provide a soft, runny yolk that enriches the mushroom base when cut.
The step that matters
Cook the mushrooms slowly until tender. Mushrooms release water and need gentle, sustained heat to soften fully and concentrate flavour. Rushing leaves them fibrous and watery, which thins the sieved base and dulls its taste.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, butter, pepper, egg):

- Onionthe original
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.
