Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Scalloped Mushrooms
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the mushrooms
Stem, peel, and wash the mushrooms.
Cook them in boiling salted water for 5 minutes.
Drain and keep hot over boiling water.
Make the sauce
In a saucepan, make a white roux by stirring the butter and flour until smooth.
Thin the roux with the hot cream or milk and add a pinch of baking soda.
When the mixture thickens, stir in the mushrooms, cayenne, nutmeg, and a little salt.
Bring the mixture to a boil.
Bake and serve
Fill ramekins or scallop shells with the mixture.
Cover with fine bread crumbs.
Dot with butter.
Bake at 400°F (200°C) until light brown.

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 dish.
- Butter
- Enriches the roux and adds richness and flavor to the topping.
- Flour
- Thickens the cream into a smooth white sauce that holds the mushrooms together.
- Cream or milk
- Forms the liquid base of the sauce, adding moisture and richness.
- Baking soda
- Raises the sauce's pH slightly, which can soften the mixture and aid browning.
The step that matters
Thickening the roux with hot cream. Adding the liquid too quickly or cold can leave lumps in the flour-based sauce. Stirring steadily while adding hot liquid lets the starch swell evenly into a smooth sauce.
Swap the nutmeg
How well each one fits the dish's main ingredients (mushroom, butter, flour, cream, pepper, bread):
- Nutmegthe original
- Parsleyfits about as well
- Thymefits about as well
- Marjoramfits less well
Fit is the average pairing score against mushroom, butter, flour, cream, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
