Ingredients

Directions

Make the custard

  1. Combine milk and lemon rind in a pan and heat until warm.

  2. Pour warm milk over beaten egg yolks. Add sugar, strain, and return to the pan.

Prepare the apple and meringue

  1. Sieve roasted apple pulp through a fine sieve and mix in lemon juice.

  2. Whisk egg whites until stiff, then gradually add 2 teaspoons of sugar and 2 teaspoons of apple pulp, whisking well.

Assemble and serve

  1. Slice sponge cakes.

  2. Layer sliced cakes in a glass dish.

  3. Soak cakes with cold custard.

  4. Pile the meringue mixture on top of the sponge cakes.

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

What each ingredient does

Egg yolks
Thicken the milk into a smooth custard when gently heated.
Egg whites
Whipped into a stiff foam that forms the light meringue topping.
Sponge cakes
Soak up the cold custard to form a moist, soft base layer.
Apples
Provide fruit flavour and body through the sieved roasted pulp.
Caster sugar
Sweetens the custard and helps stabilise the whisked meringue.
Milk
Forms the liquid base of the custard that thickens with the yolks.

The step that matters

Stir the custard until it thickens. Egg yolks set as they heat, so the custard must be stirred gently over low heat. If it gets too hot, the yolks scramble and turn grainy, which is why straining afterwards helps rescue it.

Swap the apple

How well each one fits the dish's main ingredients (milk, egg, lemon, sugar, pistachio):

  1. Vanillafits better
  2. Figfits better
  3. Cherryfits better
  4. Applethe original

Fit is the average pairing score against milk, egg, lemon, sugar, pistachio. Candidates are from the same food group and used in at least 100 recipes.
