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 ↓
Nut Wafers
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.
Make the dough
Cream the butter and sugar together in a bowl.
Add the beaten egg and mix well.
Stir in the flour and chopped nuts until combined.
Bake
Drop spoonfuls of the mixture onto buttered baking sheets.
Bake in a hot oven at 400°F (200°C) until golden.

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
- Adds fat for richness and a tender, crisp texture.
- Sugar
- Sweetens the wafers and helps them brown and crisp as they bake.
- Egg
- Binds the dough and adds structure and moisture.
- Flour
- Provides the structure that holds the wafers together.
- Walnuts or cream nuts
- Add nutty flavor and a crunchy texture.
The step that matters
Bake until golden. Thin drops of dough brown quickly because sugar caramelizes at high heat. Pulling them as soon as they are golden prevents scorching, which would make them bitter.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, egg, flour):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits about as well
- Walnutthe 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.
