Rockford Cookies

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

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

Make the dough

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

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

  3. In a separate bowl, combine flour and baking powder.

  4. Gradually add the dry ingredients to the wet mixture until a dough forms.

Shape and bake

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

  2. Bake in the preheated oven until 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
Adds fat and richness, and creaming it with sugar traps air for a tender texture.
White sugar
Sweetens the cookies and helps them brown while creaming with butter adds lightness.
Egg
Binds the dough and adds structure and moisture.
Baking powder
Releases gas to help the cookies rise and lighten.
Flour
Provides the structure that holds the cookies together as they bake.

The step that matters

Gradually add the dry ingredients. Adding flour in portions and mixing until just combined keeps the dough tender. Overmixing develops gluten, which makes cookies tough.
