Why it works: Butter and apple match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 8,692 recipes mention both. Both carry gamma-undecalactone, which smells peach, sweet. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: pastry
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).
Prepare a pie dish by placing a border of pastry around the edge.
In a bowl, mix the ground almonds, sugar, and egg yolks until well combined.
Butter the prepared dish and pour the almond mixture into it.
Assemble and bake
Pare and core the apples, placing a small piece of butter on each apple.
Beat the egg whites until frothy and spread them over the almond mixture.
Bake for 30 minutes.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much aroma chemistry they share, and how many recipes mention both.

Sugar and apple share little aroma chemistry, yet 16,440 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet almonds
- Provide the body of the almond base, giving it a moist, tender texture.
- Egg yolks
- Bind the almond mixture and enrich it, helping it set when baked.
- Egg whites
- Whipped to a froth, they add lightness and help the top set and brown in the oven.
- Sugar
- Sweetens the base and helps it brown during baking.
The step that matters
Beating the egg whites until frothy. Egg whites need to be whipped to a light foam so they hold air. Under-whipped whites stay dense and spread poorly over the base, while over-beaten whites turn dry and grainy and may not bake evenly.
Flavor stand-ins for the almond
How well each one fits the dish's main ingredients (sugar, egg, butter, apple):

- Almondthe original
- Cocoaabout as good a flavor fit
- Peasabout as good a flavor fit
Fit is the average pairing score against sugar, egg, butter, apple. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
