Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Mushroom Pie
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 400°F (200°C).
Clean and slice the mushrooms.
In a pan, melt butter and sauté the mushrooms until tender.
Make the filling
Stir in flour, then gradually add milk to create a sauce.
Season with salt and pepper.
Assemble and bake
Pour the mushroom mixture into a pie crust.
Cover with another layer of pastry, seal edges, and cut slits for steam.
Bake for 25-30 minutes until golden 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 filling and earthy flavor as they soften and release moisture.
- Butter
- Adds fat for richness and helps sauté the mushrooms and carry flavor.
- Flour
- Thickens the milk into a sauce that holds the filling together.
- Milk
- Forms the liquid base of the sauce, adding creaminess once thickened.
- Pastry for pie crust
- Encloses the filling and browns in the oven to form the crisp outer shell.
The step that matters
Thicken the sauce before filling the pie. Flour must be stirred in and the milk added gradually so starch can hydrate and thicken evenly without lumps. A thin or lumpy sauce will run out of the pie when baked and leave the filling soggy.
