A popular method of orange freezing is to put orange pieces in a large Quart can and cover them with 40% sugar thick syrup. The same method applies to lemons. The University of California, Davis, says sugar is unnecessary for frozen citrus, but it helps maintain the color and texture of the citrus. In order to reduce the added sugar, some fruits can be packaged with their own juice or water to freeze oranges or lemons. Leave a 1/2 inch head space (the gap between the fruit and the lid) so that citrus fruits and liquids expand during freezing. Wrap up a piece of wax paper and place it on the top of each jar to keep the citrus in the liquid.
