Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Plain Lemon Taffy
Ingredients
Directions
Make the syrup
Combine the sugar and water in a copper kettle and stir until it boils.
When the syrup reaches the 'crack' stage, add the lemon juice and lemon extract.
Continue boiling until the syrup begins to change color.
Set and cut
Remove from heat and pour onto a slab.
Once cool enough to handle, mark into blocks with a knife.

Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Granulated sugar
- Forms the body of the candy and provides most of its sweetness as it sets.
- Lemon juice
- Adds bright acidity that balances the sweetness of the sugar.
- Lemon extract
- Contributes concentrated lemon aroma to the candy.
The step that matters
Watch the syrup's stage and color. Sugar syrup hardens as its water boils off, so the stage it reaches sets the final texture. Boiling past the crack stage and into color change can darken and scorch the sugar, giving a bitter flavor.
