Flav-o-Rink.

A rather simple idea. Layer the ice rink on which hockey, curling, figure skating, and speed skating is played, adding flavor to the underlying surface (while keeping a suitable non-sugary ice top surface), to sell after the game or event. Of course not ALL of this surface can be cut-up and resold because of blood, sweat and other contaminates, but some unused section can go to paying fans, or even provide a tasty alternative for getting shaved ice in your face if you're playing.

Etched with your team's logo, or get it in a commemorative self-contained deep-freeze case to keep on your mantle at home. Just imagine eating the very ice that Wayne Gretzky won his final championship game on. Or enjoying the former playing surface from the olympic games. One game its lime, the next, cherry.
