Lemon Zest in gelato
Lemon zest is the finely grated aromatic outer peel of the lemon (Citrus limon), prized in gelato as a natural flavoring. It is roughly 82% water with modest solids, most of them dietary fiber, and contributes intense citrus aroma with negligible sugar, fat, and antifreeze power.

Open the balancerHow to use it in gelato
Lemon zest is a flavoring, not a structural ingredient. Because it is dosed in tiny amounts, its effect on the mix PAC, POD, total solids, and fat is negligible and it does not meaningfully soften or harden the finished gelato. Its job is aroma: grate only the yellow flavedo and avoid the bitter white albedo (pith). Add it to the base for infusion, or fold in at the end for a fresher top note. Pair with lemon juice when you also want acidity, and account for that acid, not the zest, when adjusting balance.
Origin & background
The lemon (Citrus limon) is a hybrid of citron and bitter orange that spread through the Mediterranean via Arab traders by the medieval period, with Sicily and the Amalfi Coast becoming renowned growing regions. The zest's characteristic scent comes from essential oils in the flavedo dominated by limonene, which makes up roughly 60-70% of lemon peel oil.
