Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
To Cook Mushrooms
Ingredients
Directions
Prepare the mushrooms
Wash the mushrooms in cold water and skin them if they are large.
Cut each stem across the end and check for worms by following any small holes.
Drain the cleaned mushrooms.
Make the gravy
In a saucepan, melt the butter over medium heat until it bubbles.
Stir in the flour and thin it with the milk.
Season with salt and red pepper.
Once the flour is cooked, add the mushrooms and let them boil for 2-3 minutes.
Serve
Serve the mushrooms on toast or in pastry shells.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh mushrooms
- Provide the main body and earthy flavour of the gravy.
- Butter
- Adds fat and richness and carries the flavour of the dish.
- Flour
- Thickens the milk into a smooth gravy once it is cooked.
- Milk
- Forms the liquid base that the flour thickens into gravy.
The step that matters
Cook the flour before adding the mushrooms. Flour mixed into hot butter must cook for a while to lose its raw starchy taste and to thicken properly. Adding the mushrooms too early leaves the gravy pasty and floury.
