Ingredients

Directions

Prepare the cake

  1. Cut the sponge cake into horizontal slices ½ inch thick.

  2. Divide the beaten egg whites into two portions.

  3. In one portion, stir in the coconut and half of the powdered sugar.

  4. In the other portion, mix in the almond paste and the remaining powdered sugar.

  5. Spread half of the cake slices with the coconut mixture and half with the almond mixture.

  6. Reassemble the cake, setting aside the top slice for later.

  7. Press the slices firmly together and cut out the center, leaving walls 1 inch thick.

Make the filling

  1. Soak the removed cake parts in the custard.

  2. Rub the soaked cake smooth and fold it into the whipped cream.

  3. Fill the cake with the cream mixture, replace the lid, and ice the top.

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

What each ingredient does

Sponge cake
Provides the structure that holds the filling and the shell's walls.
Egg whites
Beaten stiff, they lighten the almond and coconut layers and help them set.
Heavy cream
Whipped, it adds moisture and a light, airy texture to the filling.
Rich custard
Soaks into the cake crumbs, adding moisture and richness to the filling.
Sweet almonds
Adds nutty flavor and body to the almond layer.

The step that matters

Soaking the removed cake parts in the custard. Cake crumbs need enough custard to become moist without turning soggy. Too little leaves the filling dry, while too much makes it heavy and collapses the structure when folded into the cream.

Swap the coconut

How well each one fits the dish's main ingredients (cream, wine, almond, egg, sugar):

  1. Vanillafits better
  2. Figfits better
  3. Raisinfits better
  4. Coconutthe original

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