Good Cookies

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

  1. Preheat the oven to 350°F (175°C).

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

  3. Add the sour milk and baking soda, mixing well.

  4. Incorporate the egg yolks and baking powder.

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

  6. Flavor the dough to your liking.

Shape and bake

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

  2. Bake in the preheated oven until golden brown.

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

What each ingredient does

Sugar
Sweetens the dough and helps it brown during baking.
Butter
Adds fat that tenderizes the cookies and carries flavor.
Sour milk
Adds acidity that reacts with the baking soda to help the cookies rise.
Baking soda
Reacts with the acidic sour milk to produce gas that lightens the dough.
Egg yolks
Add richness and structure, binding the dough together.
Flour
Provides the structure that holds the cookies' shape after baking.

The step that matters

Gradually add flour until the dough is thin enough to roll out. Adding too much flour at once or too little overall changes the dough's texture. Flour gives structure, so adding it gradually lets you stop when the dough is rollable without making the cookies tough and dry.
