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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, beat the eggs and butter together until smooth.
Gradually add the sugar and mix well.
Stir in the flour until the mixture can be rolled into finger-sized shapes.
Bake and serve
Place the rolled fingers on a baking sheet, leaving space for spreading.
Bake until they are thin and lightly golden.
Flavor with lemon and serve dipped in chocolate icing.

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
- Eggs
- Bind the batter and give structure and richness as they set in the oven.
- Butter
- Adds fat for tenderness and richness, and helps the dough hold together.
- Sugar
- Sweetens the cookies and helps them brown lightly in the oven.
- Flour
- Provides the structure that lets the dough be shaped and hold its form while baking.
The step that matters
Leave space on the baking sheet. The dough spreads as it bakes and turns thin. Without room between the fingers, they can fuse together and bake unevenly.
Swap the lemon

Fit is the average pairing score against egg, butter, sugar, flour, chocolate. Candidates are from the same food group and used in at least 100 recipes.
