The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: beta-damascenone (apple, rose).

Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.

What each ingredient does

Orange juice
Supplies the flavor and acidity, and the liquid in which the sugar dissolves.
Loaf sugar
Sweetens the juice and, as it concentrates on boiling, thickens it into a syrup.

The step that matters

Boiling and skimming until creamy. Sugar concentration controls the syrup's thickness, so boiling must be stopped at the right point. Overheating can caramelize the sugar and darken the flavor. Skimming removes foam and impurities that would otherwise cloud the syrup.
