All frozen items should be held at –10°C / 14°F, except for granites and ices, which should be held at –18°C / 0°F.
Keep them covered. If they are still-frozen items, keep them in an airtight container. If they are churned or pacotized, keep them covered with a plastic lid or stainless steel lid.
Minimize the time the freezer door stays open to prevent heat shock on your frozen items.
Do not hold ice creams, sorbets, sherbets, and gelatos for more than 18 hours (2 services) for optimal quality.
Still-frozen desserts, if properly stored, will hold for 3 to 4 days.
