Why it works: Lemon and hazelnut match in chemistry and in kitchens. They rank in the top 12% of all ingredient pairs, and cooks put them together in 205 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the dough
In a bowl, cream the butter and sugar together until light and fluffy.
Add the lemon zest and mix well.
Shape and bake
Drop spoonfuls of the mixture onto a baking sheet lined with parchment paper.
Sprinkle chopped hazelnuts on top of each cookie.
Dust with sugar before baking.
Bake for 10-12 minutes or until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cookies a light, tender crumb and rich flavor.
- Sugar
- Sweetens the cookies and, creamed with butter, helps create a light, fluffy texture.
- Lemon zest
- Adds bright aromatic citrus flavor that lifts the rich butter.
The step that matters
Bake for 10-12 minutes or until lightly golden. Cookies can over-brown quickly because sugar caramelizes and browns at higher heat. Pulling them when just lightly golden keeps them tender and prevents bitterness.
Swap the hazelnut
How well each one fits the dish's main ingredients (butter, lemon, sugar):
- Almondfits better
- Pistachiofits better
- Chickpeafits about as well
- Hazelnutthe original
Fit is the average pairing score against butter, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
