Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
White Mushroom Sauce
Ingredients
Directions
Prepare the mushrooms
Prepare the mushrooms by cleaning them and soaking in lemon juice and water to whiten.
Cut the mushrooms into small pieces.
Make the sauce
In a saucepan, melt the butter and add the mushrooms until they are soft.
Stir in the Bechamel sauce and simmer for 5 to 6 minutes until done, but do not overcook to maintain color.
Rub the mixture through a fine sieve, reheat in a bain-marie, and serve with boiled chicken, turkey, or any white entrée.
For a richer sauce, add 1 pint of cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Button mushrooms
- Provide the main body and earthy flavor of the sauce once softened and sieved.
- Bechamel or allemande sauce
- Forms the creamy base that gives the sauce its body and smooth texture.
- Butter
- Softens the mushrooms in fat and adds richness and a rounded flavor.
- Lemon juice
- Acidity that helps keep the mushrooms pale during soaking.
The step that matters
Avoid overcooking after adding the Bechamel. Extended simmering can darken the mushrooms and thicken the sauce too much, dulling its white color and smooth texture.
Swap the lemon
How well each one fits the dish's main ingredients (mushroom, sauce, sugar, butter):
- Vanillafits better
