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 ↓
Delicate 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the dough
Cream the butter and sugar together until light and fluffy.
Add the baking soda and egg whites, mixing well.
Gradually add flour until the dough is soft but manageable.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake for 10-12 minutes or until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cookies a light, tender texture.
- Sugar
- Creamed with butter to aid aeration and adds sweetness and browning.
- Baking soda
- Reacts to lift and lighten the dough as the cookies bake.
- Eggs
- Whites add structure and help bind the dough.
- Flour
- Provides the structure that sets the cookies as they bake.
The step that matters
Gradually add flour until the dough is soft but manageable. Adding too much flour makes the dough stiff and dense, while too little leaves it sticky and hard to roll. Adding it gradually lets you stop once the texture is right.
