I have a pretty respectable little jello mold collection going right now. They came into my life a variety of ways: my grandmother, Ebay, friends and colleagues cleaning out their elderly parents' garages, and now, antique shops.
I prefer metal molds because I find them both easier to use and more aesthetically pleasing. In my old apartment I had metal grating covering one wall of my kitchen to hang the jello molds and some of the vintage recipe books I've also collected over the years. It was certainly a conversation piece.
I also have some plastic novelty molds (American flag anyone?) and one classic from my grandmother with removable lids in different shapes (tree, heart, etc.). These are not quite as cute but I can't bear to part with them.
So basically, I have more jello molds than your average 20-something. Probably plenty. But this weekend my partner and I were driving back from Yosemite and stopped in Sonora (there was a gold rush museum that one of us was dying to see). The shops (and the museum) were mostly closed due to the July 4th holiday and I wasn't super keen to stick around but my partner suggested we take a walk down main street and poke our heads in a few of the antique shops. Rookie mistake.
There were jello molds everywhere. Every corner I turned there were more baskets, shelves, and corners with jello molds tucked away. At one point he lost track of me only to find me seated between two shelves piled high with antiques and digging through a basket of old (legitimately old) jello molds. I had to be gently encouraged out of the store after about an hour.
But not before I picked up a few gems to add to my collection. Stay tuned.
