I used to love looking through the Betty Crocker cookbook when I was a kid.
One thing that always boggled my mind were the Molded Jell-O Salads.
Unflavored gelatin with a little lemon juice, mayo, vegetables, meat, and eggs.
Here is one receipt that I found. I doubt if I would ever make it, let me know if you do.
MOLDED VEGETABLE SALAD
1 pkg. (3 oz.) lemon or lime Jello
3/4 tsp. salt
1 c. boiling water
3/4 c. cold water
2 tbsp. vinegar
2 tsp. grated onion
1/2 c. finely chopped cabbage
1/2 c. grated carrot
1/4 c. finely chopped celery
3 tbsp. chopped green pepper
Dissolve Jello and salt in boiling water. Add cold water, vinegar and grated onion. Chill until thickened. Fold in vegetables. Pour into 3 or 4 cup mold. Chill until firm, about 3 hours. Unmold. Garnish if desired. (An 8×10 long pan may be used.)
