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 ↓
French Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Butter a pie tin and fill it with sliced apples.
Season the apples with nutmeg and sugar.
Make the batter
In a bowl, mix the egg yolks, sugar, butter, flour, baking powder, and milk to create a batter.
Pour the batter over the apples in the pie tin.
Bake and finish
Bake until done, then turn the pie upside down onto another dish.
Beat the egg whites until stiff, sweeten them, and spread over the top of the pie.
Brown the top lightly in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and help it set, while whites are whipped into a stiff topping.
- Flour
- Provides structure so the batter sets into a cake-like base around the apples.
- Baking powder
- Releases gas that makes the batter rise and turn light and airy.
- Sugar
- Adds sweetness and helps the top brown lightly in the oven.
- Butter
- Adds fat for richness and a tender crumb, and greases the pie tin.
- Milk
- Adds moisture and liquid so the flour hydrates into a pourable batter.
The step that matters
Turning the pie upside down onto another dish. The batter is soft while still warm and may break or stick if turned too early. Let it cool enough to hold its shape before inverting it, so the apples stay on top.
Swap the apple
How well each one fits the dish's main ingredients (egg, sugar, butter, flour, milk, nutmeg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against egg, sugar, butter, flour, milk, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
