Ingredients

Directions

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

Prepare the base

  1. Cream together the sugar and butter until light and fluffy.

  2. Add the flour and egg yolks, mixing until well combined.

  3. Spread the mixture onto a thin sheet of sweet pastry dough.

Bake and top

  1. Bake in a moderate oven at 350°F (175°C) until golden.

  2. Prepare a meringue by whipping the egg whites until stiff peaks form.

  3. Spread the meringue on top, creating a netting pattern with strips.

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

What each ingredient does

Sugar
Sweetens the base and helps it brown during baking.
Butter
Adds fat for a tender, rich texture.
Flour
Provides structure so the base holds its shape.
Egg yolks
Add richness and help bind the base mixture.
Egg whites
Whipped into meringue to create a light, airy topping.

The step that matters

Whipping the egg whites to stiff peaks. Egg whites must be whipped until stiff peaks form so they trap air and hold the meringue's shape. Underwhipped whites stay runny and spread, while overwhipped whites turn grainy and collapse.
