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 ↓
Mushroom Sauce
Ingredients
Directions
Prepare the mushrooms
Peel and break the mushrooms into small pieces.
Cook the mushrooms in hot water for five minutes, then drain.
Make the sauce
Make a white sauce using the mushroom liquor and cream, then add the mushrooms and reheat.
For a brown sauce, make a roux with butter and browned flour.
Stir in brown stock, mushroom liquor, salt, and pepper, and cook for ten minutes.
Dilute the egg yolk with cream, add to the sauce, then add the mushrooms and cook for another ten minutes.
Serve
Serve with beefsteak or poultry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main flavour and body of the sauce.
- Butter
- Forms the fat base of the roux, adding richness and helping thicken the sauce.
- Browned flour
- Thickens the sauce and adds a toasted, deeper colour and flavour.
- Brown stock
- Supplies the liquid base and savoury depth of the sauce.
- Cream
- Adds richness and a smooth, silky texture.
- Egg yolk
- Enriches and further thickens the sauce, giving it a smooth body.
The step that matters
Adding the egg yolk. The yolk must be diluted with cream and stirred into the sauce off the boil or on low heat. Egg proteins set when hot, so adding it directly to a boiling sauce can scramble it and leave the sauce grainy.
