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 the mushrooms
Soak mushrooms in water and lemon juice to preserve color.
Strain the mushrooms and dry them with a cloth.
If mushrooms are large, cut them into smaller pieces and rub down the cuttings.
Make the sauce
Simmer mushrooms in butter with mace, pepper, and salt for one hour.
Prepare cream thickened with rice flour.
Add the thickened cream to the mushrooms and stir until smooth.
Finish with lemon juice and white glaze or velouté sauce.

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 earthy flavor of the sauce.
- Cream
- Adds richness and moisture, forming the base of the sauce.
- Rice flour
- Thickens the cream so the sauce becomes smooth and coats the mushrooms.
- Butter
- Adds fat and flavor as the mushrooms simmer.
- White glaze or velouté sauce
- Adds body and a savory base to finish the sauce.
The step that matters
Add the thickened cream to the mushrooms and stir until smooth. Adding thickened cream too quickly or at too high a heat can cause lumps or curdling. Stirring steadily while combining keeps the starch dispersed and the sauce smooth.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, butter, pepper, cream, rice, flour, lemon):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against mushroom, butter, pepper, cream, rice, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
