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 ↓
Chocolate Jumbles
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.
Prepare
Preheat the oven to 350°F (175°C).
Make the dough
In a large bowl, cream the butter and sugar together.
Add the eggs one at a time, mixing well after each addition.
In another bowl, combine the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until stiff enough to roll out thin.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake for about 10 minutes.

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
- Butter
- Creaming with sugar traps air and adds richness and tenderness to the dough.
- Sugar
- Sweetens the dough and, creamed with butter, helps create a light, tender texture.
- Eggs
- Bind the dough and add structure and moisture as they are beaten in.
- Flour
- Provides the structure that holds the shaped dough together while it bakes.
- Baking powder
- Releases gas during baking, helping the cookies rise and turn lighter.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in stages and mixing only until combined limits gluten development, keeping the dough tender rather than tough. The dough should be stiff enough to roll out thin without sticking.
