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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Preheat the oven to 350°F (175°C).
Rub the butter into the flour until well combined.
Add the sugar, grated lemon rind, and lemon juice, mixing well.
Incorporate the eggs into the mixture until smooth.
Shape the dough into rolls the size of a middle finger.
Bake and serve
Place on a baking sheet and bake until they spread into thin cakes.
Optionally, dip in chocolate icing before serving.

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 richness and fat, giving the dough a tender, crumbly texture.
- All-purpose flour
- Provides the structure that holds the dough together and shapes the cookies.
- Sugar
- Sweetens the dough and helps it brown during baking.
- Eggs
- Bind the dough and add moisture and structure to the batter.
- Lemon rind and juice
- Add bright, aromatic acidity that balances the sweetness.
The step that matters
Incorporate the eggs into the mixture until smooth. Beating the eggs in gradually and until smooth keeps the dough evenly emulsified, so the rolls bake uniformly and spread into thin, even cakes.
