Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Apple Flan

Oven, in the book's wordsA fairly hot oven

Ingredients

Directions

The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the apples

  1. Peel, core, and slice 4 apples thinly.

  2. Combine sliced apples, butter, sugar, and lemon rind in a pan.

  3. Cook over low heat until apples become pulp, then allow to cool.

Line and fill the flan

  1. Make short pastry and line a flan ring with it.

  2. Spread the pulped apple in the pastry.

  3. Peel, core, and slice the remaining apple, then layer slices on top of pulped apple until covered.

Bake and serve

  1. Bake in a preheated oven at 400°F (200°C) until pastry is browned.

  2. Serve hot or cold.

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

What each ingredient does

Cooking apples
Form the soft pulped filling and the sliced topping, providing body and fruit flavour.
Short pastry
Forms a crisp base that holds the apple filling in its ring.
Butter
Adds richness and fat, giving the cooked apples a rounder, smoother flavour.
Sugar
Adds sweetness and helps the cooked apples and pastry brown.
Lemon rind
Adds bright aromatic citrus oils that lift the sweetness of the apples.

The step that matters

Cook the apples to a smooth pulp, then cool them. Low heat softens the apples and drives off excess moisture without scorching the butter and sugar. Cooling before filling keeps the hot, wet fruit from softening the raw pastry and melting its butter, so the base stays crisp.

Swap the lemon

How well each one fits the dish's main ingredients (butter, apple, sugar):

  1. Pearfits better
  2. Vanillafits better
  3. Apricotfits better
  4. Lemonthe original

Fit is the average pairing score against butter, apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
