3 (3 oz.) pkgs. Jello, all same flavor
3 env. unflavored gelatin
3 c. boiling water
1 c. cold water
2 tbsp. lemon juice

Dissolve Jello in hot water and set aside. In another bowl, add gelatin mixture over cup of cold water while you stir. Add lemon juice to gelatin mixture.

Combine two mixtures and pour into 8 inch square pan. Refrigerate, but do not cover. When jelled, cut into squares. This can be put in a larger pan; squares will be thinner.
