    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 peel
Forms the main body of the preserve and carries its citrus aroma and bitterness.
Sugar
Sweetens the peel and, at high concentration, helps preserve it.

The step that matters

Soak until no longer bitter. The bitter compounds in citrus peel leach out slowly into water. Changing the water removes them as they release, so stopping early leaves the peel bitter.
