https://en.m.wikipedia.org/wiki/Jello_salad

Jello salad is an American salad made with flavored gelatin, fruit, and sometimes grated carrots or (more rarely) other vegetables. Other ingredients may include cottage cheese, cream cheese, marshmallows, nuts, or pretzels. Jello salads were popular in the early 20th century and are now considered retro.

For those as lost (at first) and disgusted (from now one) as me.
