I thought Jell-O was a brand name (or so I picked up somewhere) and that jelly was the general word for it. Yeah, dessert jelly contains gelatin. I just searched images for it, and jelly did turn up with both gelatin dessert and something looking like jam. Food can be one of the most confusing differences from one country/ language to the next. Mostly because I seldom come across food words, especially not detailed ones.
