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.
Make the dough
Cream together the sugar and shortening.
Add the well-beaten egg, flavoring extract, and sifted flour mixed with salt and baking powder.
Add enough milk to form a dough that is just stiff enough to roll without sticking.
Shape and bake
Roll the dough to a thickness of ¼ to ½ inch and cut into desired shapes.
Bake in a preheated oven at 400°F (200°C) until delicately browned, about 10 to 12 minutes.

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
- Sugar
- Sweetens the dough and helps it brown lightly in the oven.
- Flour
- Provides the structure that holds the cookies together after baking.
- Shortening
- Adds fat for tenderness and a short, crumbly texture.
- Baking powder
- Releases gas during baking so the cookies rise slightly and stay light.
- Egg
- Binds the dough and adds richness and structure.
- Milk
- Adds moisture so the flour hydrates and the dough comes together.
The step that matters
Adding the milk. Too much milk makes the dough sticky and hard to roll and cut, while too little leaves it crumbly. Add it gradually until the dough is just stiff enough to roll without sticking.
