Why it works: Mushroom and beef are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Brown Mushroom Sauce
Ingredients
Directions
Prepare the mushrooms
Remove caps from the mushrooms, wipe and peel them.
Cut the mushroom stems into pieces, cover with cold water, and bring to a boil.
Boil for 20 minutes.
Drain the stems, reserving the liquid (you should have ½ cup).
Make the sauce
Melt the butter in a pan, add onion juice, and cook until slightly browned.
Stir in the flour gradually, then pour in the cream and reserved mushroom liquor while stirring constantly.
Add the beef extract and season with salt and paprika.
Finish and serve
Slice the mushroom caps and sauté them in butter for 5 minutes.
Add the sautéed mushroom caps to the sauce just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and cream into a smooth, body-rich sauce as it cooks.
- Butter
- Carries the onion flavour and gives richness and a smooth mouthfeel to the sauce.
- Cream
- Adds richness and moisture, helping the sauce feel silky and full.
- Mushroom liquor
- Adds concentrated mushroom flavour and moisture to the sauce base.
- Beef extract
- Adds savoury depth and a meaty, umami-rich backbone to the sauce.
The step that matters
Stirring the flour into the butter and adding the liquids. Flour must be stirred in gradually and the cream and liquor added while stirring constantly, so starch disperses evenly and gelatinises without lumps forming as the sauce thickens.
Swap the onion
