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 ↓
Fruit Glace
Ingredients
Directions
Make the syrup
Boil sugar and lemon juice for 30 minutes.
Dip a skewer into the syrup, then dip the skewer into water; if the thread breaks off brittle, the syrup is ready.
Prepare the fruit
Pare and divide oranges into eighths, wiping them dry.
Coat the fruit
Pour part of the syrup into a small cup.
Place the cup in boiling water.
Skewer each piece of orange and dip it into the syrup.
Place the orange pieces on a lightly buttered dish.
Prepare grapes and nuts the same way.
Do not stir the syrup to avoid spoiling it.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Forms the syrup that cooks to a hard, brittle glaze that sets on the fruit.
- Lemon juice
- Acidity helps keep the boiled sugar syrup smooth and less prone to crystallising.
- Oranges
- The fruit pieces are the base that the glossy syrup coats and sets on.
The step that matters
Judging when the syrup is ready. The skewer and water test decides when the syrup is ready. If it is not cooked long enough the glaze stays sticky, and stirring can encourage sugar to crystallise, so the syrup is left unstirred.
