Preparation Select firm, tree-ripened fruit heavy for its size and free from soft spots. Wash and peel. Divide fruit into sections, removing all membranes and seeds. Slice oranges if desired. For grapefruit with many seeds, cut fruit in half and remove seeds; cut or scoop out sections.
Juice Select fruit as directed for sections. Squeeze juice from fruit, using squeezer that does not press oil from rind.
Sweeten with 2 tablespoons sugar for each quart of juice or pack without sugar. Pour juice into containers immediately. To avoid development of off-flavors, pack juice in glass jars. Leave headspace. Seal and freeze.
For more information, see other unsweetened packs.
