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.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the butter and sugar.
Add the cold water and mix well.
Incorporate the eggs and baking soda.
Gradually add flour until the dough is thick enough to roll.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake until lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add fat and tenderness to the cookies.
- Sugar
- Creams with the butter and adds sweetness and helps the cookies brown.
- Eggs
- Bind the dough and add structure as it sets in the oven.
- Baking soda
- Reacts to help the cookies rise and spread and encourages browning.
- Flour
- Provides the structure that lets the dough be rolled and cut.
The step that matters
Gradually add flour until the dough is thick enough to roll. Adding too much flour at once or too little overall changes the dough's texture. Adding it gradually lets you stop when the dough is firm enough to roll without becoming tough and dry.
