Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Cream the butter and sugar together.

  2. Add the flour and eggs, mixing until combined.

  3. Freeze the dough overnight if possible.

Shape and bake

  1. Roll out the dough very thin.

  2. Brush with egg white.

  3. Sprinkle with a mixture of granulated sugar and cinnamon.

  4. Add nuts on top.

  5. Bake in a 400°F (200°C) oven until golden.

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

What each ingredient does

Butter
Creams with sugar to give the dough richness and a tender, crumbly texture.
Eggs
Bind the flour and butter into a dough and add richness to the cookie.
Flour
Provides the structure that holds the dough together as it bakes.
Sugar
Sweetens the dough and helps it brown during baking.
Egg white
Brushed on top, it helps the sugar and cinnamon stick and gives a glossy, crisp finish.

The step that matters

Roll out the dough very thin. Thin dough bakes quickly into a crisp cookie. Thicker dough stays soft and doughy in the center and may not brown evenly before the edges overbake.

Swap the nuts

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits better
  4. Nutsthe original

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