Harvest before seeds become mature and when color is uniformly dark. 
Wash, peel and slice 1/3 inch.  Prepare quickly; just enough eggplant for 1 scalding at a time.   Scald 4 minutes in 1 gallon boiling water containing 4-1/2 teaspoons citric acid or 1/2 cup lemon juice.
 Cool, drain and pack in can or
freeze jars or plastic freezer boxes. 
For frying: Pack the drained slices with freezer wrap between slices.  Seal, label and freeze.
