There’s always room for Jell-O… cookbooks! As colorful and light as the iconic dessert itself, these recipe booklets were given out as free promotional items starting in 1904, and played a large part in Jello’s meteoric and jiggly rise to fame. Some feature illustrations by artists like Maxfield Parrish and Norman Rockwell; all contain congealed concoctions like Jell-O Chicken Mousse or Shrimp & Orange Jell-O Molds – possibly chic at the time, but disturbing to most modern palettes.  Through these culinary collectables we can trace the history of advertising and even social life  in the United States, as the pamphlets gradually pivot from addressing nervous young housewives to exhausted working mothers. Photogenic and squeam-inducing, retro Jell-O recipes are enjoying a semi-ironic online renaissance, popping up on twitter accounts like @70s_party, the cheekily named facebook group Show Me Your Aspics, and even in contemporary art. Listen to learn more (but don’t ever learn what it’s made from!) on a #brattlecast that truly breaks the mold.
