I have a wedding coming up with mini milkshakes and mini baked Alaskas. I’d like to keep them cold in some sort of dry ice thing. I’ve done some stuff with it in the past, but it wasn’t really functional, only for show. I would kind of like it to be functional. I tried putting dry ice in a 400 pan with a perforated on top with the milkshakes in there. It doesn’t look that pretty and the dry ice doesn’t last unless you shake it or add more. Should I just display these things on regular crushed ice with just the dry ice behind it for effect? Any good ideas on a cool way to display frozen items?
