Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

  1. Preheat the oven to 400°F (200°C).

  2. In a bowl, cream together the sugar and butter.

  3. Add the egg and sweet milk, mixing well.

  4. Stir in the baking powder.

  5. Gradually add flour until the dough is firm enough to roll out.

Shape and bake

  1. Roll out the dough and cut into desired shapes.

  2. Bake quickly until lightly golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 richness and a tender texture to the cookies.
White sugar
Creams with the butter and adds sweetness and gentle browning.
Egg
Binds the dough and adds structure and richness.
Baking powder
Releases gas to lighten the dough and help it rise in the oven.
Sweet milk
Adds moisture so the dough comes together smoothly.

The step that matters

Bake quickly until lightly golden. Baking at a high oven temperature for a short time sets the outside while keeping the cookies tender. Overbaking dries them out and turns them hard and brittle.
