As I've gotten older I've learned to appreciate things like molded (savory) jello salads and aspics and such things.
I haven't actually opened up a cookbook in decades, but I'll check out a couple of my favorite cookbooks put out by Ladies Brigades or organizations full of potluck recipes and such. I know I have several good ones.
I have my mid-century modern appreciation and believe in Jello as an art form, if I can bring one to a party or potluck I do fancy molded but fruity/sweet ones. The type that serve 20, I like a single serving so happy for parties but too much of a good thing without one.
