what temperature to keep freezer at
1 When ice cream's small ice crystals melt and re-freeze, they can eventually turn into large, unpalatable lumps. 2  Your freezer should be set at between -5Â°F and 0Â°F. Ice cream is easy to dip between 6Â°F and 10Â°F, the ideal serving temperature range.  Store ice cream in the main part of the freezer.
