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 ↓
Mushrooms and Eggs
Ingredients

Make the mushroom base

Add butter, chopped onion, herbs, salt, and pepper to taste.
Press the mixture through a sieve and place it on a plate.
Serve
Carefully cover with poached eggs.
Sprinkle with pepper and salt before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and earthy flavour of the base when cooked down until tender.
- White stock
- Cooks the mushrooms gently and adds savoury liquid that carries flavour into the base.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the pressed mushroom mixture.
- Onion
- Adds sweetness and aromatic depth to the mushroom base as it softens.
- Poached eggs
- Add a soft, runny yolk that enriches the mushroom base when cut into.
The step that matters
Pressing the mixture through a sieve. Pushing the cooked mushrooms and onion through a sieve breaks down their fibres into a smooth purée. Skipping or rushing this leaves a coarse texture instead of a silky base.
Swap the onion
