Why it works: Sugar and nuts 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
Make the syrup

Pour syrup into a straight-sided pan, 1 inch deep.
Crystallize and dry
Gently drop in the nuts, ensuring they do not touch each other.
Set aside in a dry, moderately warm place for 24 hours.
Drain syrup from the pan.
Place the pan in a cool area until nuts are dry.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Granulated sugar
- Dissolves into syrup that recrystallizes as a hard, sweet, crisp coating on the nuts.
The step that matters
Boil the syrup until a drop forms a ball in ice water. The sugar concentration set by boiling determines how the sugar recrystallizes on the nuts. Stopping too early leaves a sticky coating that stays soft, while boiling too long makes the coating brittle and prone to cracking.
