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 ↓
Canned Mushrooms in Sauce
Ingredients
Directions
Prepare
Drain the mushrooms from their liquid.
Make the sauce
In a small frying pan, melt the butter over medium heat.
Add the mushrooms, season with pepper and salt, and fry until slightly colored.
Push the mushrooms to one side of the pan and add the flour, rubbing it smooth in the hot butter.
Once the flour is slightly browned, gradually pour in the mushroom liquor and a few spoonfuls of water.
Add the mushrooms back to the pan, bring to a boil, and squeeze in the lemon juice.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and savory flavor of the sauce.
- Flour
- Thickens the liquid into a smooth sauce as it cooks in the butter and liquor.
- Butter
- Carries the frying of the mushrooms and gives the sauce richness.
- Mushroom liquor
- Adds concentrated mushroom flavor and liquid to the sauce.
The step that matters
Rubbing the flour smooth in the hot butter. Flour added to hot fat must be worked smooth and cooked briefly; otherwise it clumps and tastes raw. Gradually adding liquid then lets the starch swell evenly into a smooth sauce.
Swap the lemon
How well each one fits the dish's main ingredients (mushroom, butter, pepper, flour):
- Lemonthe original
- Plumfits about as well
- Limefits less well
- Cherryfits less well
Fit is the average pairing score against mushroom, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
