metal chilling pucks?

[heather s]

I'm looking at options for keeping cheese at regulatory temps when selling at a market and a friend mentioned something he's seen before - metal (stainless I guess) solid pucks or cylinders that can be put in the freezer and act then as chill units - retaining the cold temp longer than the typical plastic gel filled chill packs. Does anyone know what these are technically called and where they can be sourced? Thanks for any leads!

It looks like it would take a bunch of those to keep anything of size cool however.

Thanks for that! I wonder if they keep cool longer than the bog standard plastic things. You're right though, not very big - but then it would only be for the underside of a tray of cheese, guess that would involve 6 or so.
