Given that this and the other few threads on jello are pretty old, I just wanted to let everyone know who goes searching for jello will NOT find them in the places suggested in Zurich.
It's no longer sold at El Maiz, Globus, or Jelmoli in Zurich. I went to all of these stores, and nada :P
However, I did find it at a local market in Bern called "Merdan" (http://www.merdan.ch/
). It's not the typical Jello brand. I didn't end up buying it so I can't confirm whether it's good or not, but it can't be too hard to mess up Jello
I thought I'd share my knowledge since it cost me a couple of hours of my life
