Why it works: Raisin and cinnamon are a kitchen classic. They rank in the top 2% of all ingredient pairs, and 5,390 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. 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)

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the filling

  1. Boil the apples with sugar and white wine or lemon juice until they are stewed to a pulp.

  2. Stir continuously until the mixture thickens and dries.

  3. Mix in the almonds, candied rind, raisins, and spices until well combined.

Assemble and bake

  1. Roll out the butter crust to a thickness of about ¼ inch.

  2. Cut the crust into 4-inch squares.

  3. Brush the edges of each square with beaten egg.

  4. Fill each square with the apple mixture.

  5. Cover each filled square with another square of pastry.

  6. Press the edges securely together.

  7. Make a small incision in the top of each pastry.

  8. Bake in a slow oven at 300°F (150°C) until the raisins are tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Apples
Break down into a pulp that forms the soft, moist body of the filling.
Sugar
Adds sweetness and helps the apple mixture thicken as moisture cooks off.
Almonds
Add richness and a nutty flavor and body to the filling.
Raisins
Add chewy texture and concentrated sweetness to the filling.
Butter crust
Forms a rich, flaky pastry that encloses the filling and browns in the oven.
White wine or lemon juice
Adds acidity that brightens the apples and balances the sweetness.

The step that matters

Stir continuously until the mixture thickens and dries. Stewed apples hold a lot of water. Stirring while it reduces keeps the mixture from scorching on the base and gives a thick filling that will not leak or make the pastry soggy.

Fit is the average pairing score against apple, sugar, white wine, almond, orange, cinnamon, butter. 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).
