Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main earthy flavor and body of the sauce.
- Butter
- Adds fat and richness and carries flavor when the stems cook in it.
- Flour
- Thickens the sauce as its starch swells in the hot stock.
- Brown stock
- Forms the liquid base and adds savory depth to the sauce.
- Truffle
- Adds a strong aroma to the finished sauce.
The step that matters
Gradually pour in the brown stock.. Adding the stock slowly while stirring lets the flour disperse evenly, so the starch thickens smoothly instead of forming lumps.
