I did my first layered Jello last night and it turned out ok. After doing one, I realize how simple it is...though must be allotted a healthy amount of time to do something complicated. I found that when I poured a new layer onto the one that was set, there was some melting of the original layer. Is there any way to minimize this? I was thinking about freezing the already set products....also about chilling the molten jello to the point where it almost can't be poured, but I don't know what that temperature is. Any suggestions?
