Why it works: Barley and lemon work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 484 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Barley Sugar Drops
Ingredients
Directions
Make the drops
Boil the barley sugar until ready.
Add the rasped rind of 1 or 2 lemons to the boiling mixture.
Drop the syrup onto a marble surface in small round drops, about the size of a shilling.
Let the drops cool completely.
Store
Once cooled, store them in paper, dusting with powdered sugar as you remove them from the marble.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley sugar
- Forms the clear, hard candy base once boiled into syrup.
- Lemon rind
- Adds aromatic citrus flavour to the boiled sugar.
- Powdered sugar
- Dusted on the drops so they do not stick together or to the paper.
The step that matters
Drop the syrup onto the marble. Syrup must be hot and at the right thickness so the drops hold a round shape and set without spreading. Cooling completely before handling keeps the drops firm and stops them sticking.
