I have a myog caldera cone that I use with the Heineken keg-can. I use a silicone bracelet of the "live-strong" variety to secure the keg-can in the cone. While this keeps everything functional... it is still VERY hot after it reaches around a simmer (especially if you are boiling a full two cups) and I definitely can't pick up and pour the water in the can from the band with out burning myself. I actually tried stacking the silicone bands to see if I could grab it then, but it is still burn-status hot even with that addition.
With a second silicone bracelet at the lip of the pot, an AGG aluminum clamp handle (around 1.25 ounce) works well and doesn't damage the can at all. While this works great, it is a bit heavy respectively to the rest of the stove set-up.
What are the rest of you using to remove your keg-cans from your stove system and pour?
