A classy version of the reusable blue gel ice packs that we have seen used for camping. The Oggi thermo tray wraps a temperature sensitive gel core in stainless steel for when you want to serve hot or cold food but need to keep it sitting out for a little while.

Rather than using flame or ice, a few minutes in the oven or a few hours in the fridge with this tray will do the job.
