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
In a frying pan, melt the butter over medium heat.
Add the flour and stir until smooth and slightly browned, but do not burn.
Pour in the soup stock and the liquid drained from the mushrooms, stirring carefully to avoid lumps.
Add the salt and pepper, and cook for a few minutes.
Stir in the mushrooms and simmer for an additional 5 minutes before serving hot.
For a thicker sauce, mix in more flour wet with water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it cooks and gives it body, especially when browned lightly first.
- Butter
- Carries the flour and adds richness and flavor to the sauce base.
- Mushrooms
- Provide the main earthy flavor and savory bulk of the sauce.
The step that matters
Stirring the flour into the butter and liquid. Flour clumps when added to hot liquid without steady stirring. Cooking the flour in butter first coats the starch granules so they disperse evenly, and adding the liquid gradually while stirring keeps the sauce smooth.
