Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, cream together the granulated sugar and butter until smooth.
Add the buttermilk and baking soda, mixing well.
Gradually add flour until the dough is very soft.
Shape and bake
Roll the dough thin and cut into desired shapes.
Bake in a hot oven at 400°F (200°C) until lightly golden.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Granulated sugar
- Sweetens the dough and helps it brown and crisp during baking.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender texture.
- Buttermilk
- Adds moisture and acidity that works with the baking soda to lift the dough.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the cookies rise and spread.
- Flour
- Provides structure, which sets the dough's softness and the cookies' final shape.
The step that matters
Gradually add flour until the dough is very soft. Flour absorbs liquid and builds gluten, so adding it too quickly or too much can make the dough stiff and the cookies tough. Stopping once the dough is very soft keeps the texture tender.
