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.

Prepare

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

Make and bake

  1. In a bowl, mix the granulated sugar, egg whites, almond paste, and flour until well combined.

  2. Spread the mixture on a thin sheet of sweet pastry dough about ½ inch thick.

  3. Bake in the preheated oven until set.

Cool and cut

  1. Allow to cool, then cut into penny oblongs.

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

What each ingredient does

Egg whites
Provide structure and lift, setting the mixture as it bakes.
Almond paste
Supplies the main almond flavour and a dense, moist texture.
Granulated sugar
Adds sweetness and helps the mixture bake to a tender, browned surface.
Flour
Gives the mixture body so it holds its shape while setting.

The step that matters

Baking until set. Underbaked filling stays wet and sticky in the middle, while overbaking dries it out and makes it crumbly. Watch for the surface to firm so the slices hold together when cut.
