Why it works: Butter and mushroom 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce and, browned in butter, adds a nutty depth of flavour.
- Butter
- Adds fat and richness and helps the flour brown in the pan.
- Brown stock
- Forms the liquid base of the sauce and carries its savoury flavour.
- Mushrooms
- Add earthy flavour and body to the sauce.
The step that matters
Stirring the flour into the butter until well browned. Flour and fat cook together to form a roux. Cooking it until browned develops nutty flavour, but it can scorch quickly over medium heat, so stir constantly. Adding stock to a roux cooked this way also helps it blend smoothly without lumps.
