Lemon and sugar 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

Oranges
Provide the main fruit that is preserved whole in sugar syrup.
Lemons
Add tart acidity that balances the sweetness of the syrup.
Sugar
Makes the syrup that preserves the fruit and gives it sweetness.
Coarse sea salt
Draws out bitterness and moisture during the saltwater soak.

The step that matters

Simmering the fruit in sugar syrup until clear. Simmering gently lets sugar slowly replace the water in the rind and pulp, which preserves the fruit and makes it translucent. Boiling hard can break the fruit apart and make the syrup cloudy, so the heat should stay low enough to keep the pieces whole.
