Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Preheat the oven to 350°F (175°C).

  2. Cream the egg yolks and sugar together.

  3. Stir in the beaten egg whites, chocolate, cracker dust, baking powder, and walnuts.

Bake and fill

  1. Bake in two layers.

  2. Fill with whipped cream.

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

What each ingredient does

Eggs
Egg yolks and whipped whites give structure, moisture, and lift to the batter.
Sugar
Creamed with the yolks, it adds sweetness and helps give the batter body.
Baking powder
Releases gas in the batter, helping the tart rise and turn lighter.
Walnuts
Add crunch and nutty flavor that contrast with the soft interior.
Chocolate
Adds richness and deep flavor to the batter.

The step that matters

Stir in the beaten egg whites. Beaten whites hold air bubbles that help the tart rise. Folding them in gently, rather than stirring hard, keeps that air from collapsing and leaves the layers light.

Swap the walnut

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

  1. Pecansfits better
  2. Almondfits better
  3. Hazelnutfits about as well
  4. Walnutthe original

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