Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main flavour and, once pounded and sieved, body to the sauce.
- Corn flour
- Thickens the milk into a smooth sauce as it heats and boils.
- Butter
- Adds richness and fat, and helps the flour blend smoothly.
- Milk
- Forms the liquid base of the sauce and softens the mushrooms.
The step that matters
Stir the flour into the butter until smooth, then add the liquid gradually. Starch granules clump if hot liquid meets them unevenly. Cooking the flour briefly in fat and stirring while the mixture comes to the boil keeps the sauce smooth and fully thickened.
Swap the white pepper
How well each one fits the dish's main ingredients (corn, flour, butter, milk, mushroom, nutmeg):
- Cinnamonfits better
- Cardamomfits better
- Marjoramfits better
- White pepperthe original
Fit is the average pairing score against corn, flour, butter, milk, mushroom, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
