Why it works: Hazelnut and sugar work together. They rank in the top 20% of all ingredient pairs, and cooks put them together in 649 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 300°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Grind the hazelnuts until they form a paste.
Mix in the sugar and icing sugar.
Add the raw egg whites and let the mixture rest covered for 2 days.
Before piping, add the cooked sugar or apricot.
Pipe and bake
Pipe onto parchment paper in the size of small cookies.
Bake on a double tray, covered with a damp cloth, in a gentle oven (300°F/150°C).
Finish
Once baked, pair them with fondant mixed with apricot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hazelnuts
- Provide the main nutty flavour and the bulk of the dry structure of the shells.
- Egg whites
- Provide the protein structure that holds the batter together and helps the shells rise.
- Sugar
- Adds sweetness and helps give the shells a crisp, glossy crust.
- Icing sugar
- Adds sweetness and a fine texture to the batter.
- Cooked sugar
- Adds moisture and body to the batter, helping it hold its shape before baking.
The step that matters
Resting the batter for 2 days. Resting lets the egg whites and sugars dry slightly, forming a skin on the shells. This skin helps them rise evenly and form feet rather than cracking or spreading during baking.
Swap the hazelnut
How well each one fits the dish's main ingredients (sugar, egg):
- Pecansfits better
- Almondfits better
- Chestnutfits about as well
- Hazelnutthe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
