Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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.
Make the dough
In a bowl, cream together the sugar and butter.
Add the eggs and mix well.
Stir in the chopped nuts and baking soda.
Gradually add flour until the dough is thin enough to roll out.
Roll out the dough and cut into desired shapes.
Finish and bake
Frost the cookies and place nuts on top.
Bake until golden brown.

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
- Sugar
- Adds sweetness and helps the cookies brown in the oven.
- Butter
- Adds fat for flavor and a tender texture.
- Eggs
- Bind the dough and add structure as they set.
- Baking soda
- Reacts to lift and loosen the dough so it rises and spreads.
- Flour
- Builds the structure that lets the dough be rolled and cut.
- Chopped nuts
- Add crunch and a toasty, nutty flavor.
The step that matters
Gradually add flour until the dough is thin enough to roll out. Adding flour gradually lets you stop at the right consistency. Too much flour makes the dough stiff and the cookies dry and tough, because extra flour absorbs moisture and develops more structure.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, butter, egg, flour):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
