Completely dissolve gelatin in boiling water. Combine cold water and the ice cubes to make 1.25 cups. Add to gelatin with lemon juice, stirring until slightly thickened. Remove any unmelted ice. Fold in vegetables. Spoon into individual dessert cups. Chill until set about 30 minutes. Additional Combinations: Along with the sliced celery try grated carrots and golden raisins; or chopped cucumber and chopped pimientos; or drained mandarin orange sections and chopped green pepper. Or possibly use the celery and chopped cabbage, chopped apple or sliced ripe or green pitted olives. == Courtesy of Dale & Gail Shipp, Columbia Md. ==
