Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ingredients
Directions
Make the syrup
Make a syrup by boiling water, sugar, and lemon juice in a porcelain-lined kettle for 30 minutes without stirring.
Test the syrup by dropping a little into cold water; if it hardens and becomes brittle, it's ready.
Pour the syrup into a small dish and keep it liquid by placing it in a pan of boiling water.
Coat the fruit
Dip fruits into the syrup, coating them thoroughly, and place them on buttered paper to harden.
For oranges, divide them into sections, skewer them, and dip them in the syrup.
Use a skewer to dip fruits without stems to avoid burning your fingers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the syrup that hardens into a crisp, glassy coating on the fruit.
- Lemon juice
- Adds acidity that helps keep the boiled sugar syrup from turning grainy.
- Water
- Dissolves the sugar so it can be boiled into a syrup.
The step that matters
Testing the syrup. Sugar syrup must reach the correct concentration to set brittle when cooled. Too little cooking leaves a sticky coating that never hardens, while too much cooking makes it bitter or dark. The cold water test shows when it is ready.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, lemon, grape, banana, orange, peach):
- Almondfits better
- Pistachiofits about as well
- Walnutthe original
- Chestnutfits about as well
Fit is the average pairing score against sugar, lemon, grape, banana, orange, peach. Candidates are from the same food group and used in at least 100 recipes.
