Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Mushroom Sauce
Ingredients
Directions
Prepare
Clean and slice the mushrooms.
In a saucepan, melt the butter over medium heat.
Make the sauce
Add the mushrooms, salt, pepper, and lemon juice.
Cook until the mushrooms release their liquid.
Stir in the flour to thicken the sauce.
Add enough cream to achieve a white sauce consistency.
For a brown sauce, fry the mushrooms in butter until golden.
Then stew the browned mushrooms in strong gravy.
Serve
Serve the sauce with chicken or other white meats, garnished with lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while the mushrooms cook.
- Mushrooms
- Provide the main body and earthy flavour of the sauce as they release their liquid.
- Flour
- Thickens the sauce as it cooks with the butter and mushroom liquid.
- Cream
- Adds richness and smoothness, giving the white sauce its creamy texture.
- Lemon juice
- Adds acidity that brightens the flavour of the mushrooms and cream.
The step that matters
Adding the cream. Cream should be added gradually after the flour has thickened the mushroom liquid. Adding it too early or too fast can thin the sauce or cause it to split, so the consistency may be hard to correct once it has gone wrong.
Swap the mace
How well each one fits the dish's main ingredients (butter, mushroom, pepper, lemon, flour, cream, nutmeg):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against butter, mushroom, pepper, lemon, flour, cream, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
