Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Plain Rolled Cookies
Ingredients
Directions
The book says “a rather hot 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).
Cream together the sugar and shortening.
Add the beaten egg, flavoring extract, salt, and baking powder to the mixture.
Gradually add the sifted flour and enough milk to form a dough that is stiff enough to roll out.
Shape and bake
Roll the dough to about ¼ inch thickness and cut into desired shapes.
Bake for 10 to 12 minutes until delicately browned.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cookies together as they bake.
- Shortening
- Creaming with sugar traps air and makes the cookies tender and short.
- Sugar
- Sweetens the dough and, creamed with fat, helps give a light texture and browning.
- Baking powder
- Releases gas during baking, helping the cookies rise and lighten.
- Egg
- Binds the dough and adds moisture and structure as it sets in the oven.
- Milk
- Adds moisture so the flour forms a dough that can be rolled out.
The step that matters
Adding the milk gradually. Flour hydrates as it is mixed, so adding milk a little at a time lets you reach a dough that is stiff enough to roll without becoming tough from overworking the gluten.
