Completely dissolve gelatin in boiling water. Combine cold water and the ice cubes to make 1 1/4 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. ==
