Oh I remember that peanut butter spread. I think there was a banana flavor too.
When I was a kid we had jello, whip-n-chill, which was pretty much poor white trash instant flan, and this three-layer thing that you would mix up from a single envelope, and the three layers ’emerged’ I guess due to their relative weight? The top was translucent gelatine and the bottom was pretty much whip-n-chill. I liked that stuff at the time but I’m sure I’d think it was inedible today.
