Why it works: Nuts and sugar are a kitchen classic. They rank in the top 25% of all ingredient pairs, and cooks put them together in 2,228 recipes. Both carry 1-penten-3-one, which smells fish, pungent. 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.
Prepare
Crack the Barcelona nuts and place the kernels in a copper pan.
Roast the nuts in a 350°F (175°C) oven until golden.
Make the coating
In a separate pan, combine sugar and water; boil until almost caramelized.
Add the roasted filberts to the syrup and stir until fully coated.
Cool and serve
Allow to cool and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barcelona nuts
- Provide the main body of the confection, toasted for a deeper, nutty aroma.
- Sugar
- Forms the caramel that coats the nuts, adding sweetness and a glossy, brittle shell.
- Water
- Dissolves the sugar so it can boil evenly into syrup before caramelizing.
The step that matters
Boil the sugar syrup until almost caramelized. Sugar darkens quickly near the end of cooking, so it can turn bitter or burnt if left too long. Stopping just short of full caramelization keeps the flavor balanced and lets the syrup coat the nuts evenly as it cools and hardens.
