Why it works: Sugar and walnut are a kitchen classic. They rank in the top 26% of all ingredient pairs, and cooks put them together in 7,147 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

What each ingredient does
- Granulated sugar
- Forms the hard, glassy candy coating as it boils and then cools.
- Walnuts or butternuts
- Form the centre of each piece, adding crunch and nutty flavour beneath the crisp shell.
The step that matters
Do not stir the sugar while boiling. Stirring hot sugar syrup can trigger crystallisation, making the candy grainy and cloudy instead of smooth and glassy. Let it boil undisturbed until it reaches the crack stage.
