I'm looking to buy some 'boiling off' pans. Stainless flat trays really is all I need. I'm using some big turkey pans which work OK but would like even more surface area. I have a commercial gas stove (big 6 burner kind) I'd love to get a stainless tray with low sides that would span two burners at once. That would really speed up the boil. Would it be hard for someone to fabricate some crude pans? Just need like a 12x32 or 12x36 flat plate steel bottom then could weld some 3" sides all the way around and then, of course, be sure the welds don't let loose....
