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

In a bowl, cream together the butter and sugar.
Beat in the egg and almond extract until well combined.
Gradually add the flour and mix until a dough forms.

Shape and bake

Roll the dough into small balls and dip each in white sugar.
Place on a baking sheet lined with buttered paper.
Bake at 400°F (200°C) until lightly golden.

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

What each ingredient does

All-purpose flour: Provides the structure that holds the cookie dough together as it bakes.
Unsalted butter: Adds fat for tenderness and richness, and helps the cookies brown.
White sugar: Sweetens the cookies and helps them brown and crisp at the edges.
Egg: Binds the dough and adds moisture and structure.
