Orange Zest in gelato
Orange zest is the fresh, finely grated outer colored peel (flavedo) of the sweet orange, prized for its intense citrus aroma. In gelato it is a flavoring and aromatic ingredient rather than a structural one, used in trace amounts to add bright orange top-notes.

Zest only the colored flavedo and avoid the white albedo underneath, which is bitter. Grate it finely into the base, or infuse it in the warm mix and strain, to release the aromatic essential oils. Because it is dosed at only a few grams per kilogram, its contribution to sugar, solids, POD and PAC is negligible, so it does not require rebalancing your base; treat it as pure flavor. Add it late or infuse gently to protect the volatile top-notes, and pair with orange juice or an orange compound when a fuller, sweeter orange body is wanted.
Origin & background
The sweet orange (Citrus sinensis) is a hybrid of pomelo and mandarin, cultivated for over two thousand years and carried from Asia to the Mediterranean by traders during the 15th and 16th centuries. Citrus peel has long been central to Italian and Sicilian confectionery, where candied and grated orange peel flavors cakes, panettone and gelato. The zest holds the essential-oil glands that give the fruit its characteristic fragrance.
