Drain borscht; heat 1 1/2 cups of the liquid; dissolve gelatin in hot borscht. Add sugar, vinegar and remainder of cold borscht juice. Chill until somewhat thickened. Blend in 2.5 oz- full 5 oz jar of undrained horseradish. Fold in beets. Spoon into 6 cup mold. Chill
Optional: add 1 lb jar of drained and diced geflite fish with the horseradish and beets. Spoon into a 2 quart mold. If using a fish mold use slivers of black olives for eyes.
