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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter and sugar together until well combined.
Add the water and stir until mixed, then add the beaten egg.
Sift the flour and add it to the mixture, stirring until smooth.
Stir in the chopped nuts and baking powder until well combined.
Bake
Drop spoonfuls of the mixture onto buttered baking sheets.
Bake at 400°F (200°C) 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
- Butter
- Creams with the sugar to give the drops a tender, rich texture.
- Sugar
- Creamed with the butter and adds sweetness and browning.
- Egg
- Binds the dough together and adds structure as it sets in the oven.
- Flour
- Provides the main structure that holds the drops together as they bake.
- Baking powder
- Releases gas in the dough, helping the drops rise and lighten as they bake.
- Nuts
- Add crunch and a toasted, nutty flavour to the baked drops.
The step that matters
Bake until golden brown. Baking at 400°F sets the drops quickly. Pulling them too early leaves the centres doughy, while overbaking dries them out and makes them hard.
Swap the nuts
How well each one fits the dish's main ingredients (butter, sugar, egg, flour):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
