In the 1950s and 1960s, ice cream and Jell-o were allies in dessert.
While both were discontinued in the early days of World War II, that wasn’t the end for the interaction of ice cream and the Jell-o brand. Although Jell-o marketed ice-cream-and-gelatin desserts in the 1940s, they didn’t really catch on until the late 1950s and early 1960s.
For example, here’s Johnny Carson in 1957 from the set of Do You Trust Your Wife, demonstrating how to make an ice cream pie:
But “fingertip Jell-o” didn’t come along until around the 1970s, although the early versions were marketed by Knox under the name Knox Blox. These were firmer than what the 1980s and ’90s kids know as “Jell-o jigglers,” but some recipes, like this one, used both to achieve a gelatin firm enough to handle, but soft enough to avoid the kind of bounciness that Knox Blox sometimes had.
A basic version appeared in the August 17, 1978 edition of the Orrville (Ohio) Courier Crescent:
4 envelopes Knox gelatin
Mix together the above dry ingredients and stir this until the Jell-o mixture melts. Then pour into a long cake pan and chill for one hour. Mrs. Ayers says her children like to cut the Jell-o with cookie cutters. “It’s great for summer and picnics, especially since it doesn’t melt,” she says.
