Mongolian hotpot, shabu shabu, steamboat, asian cooker.These work like a thermette, kelly kettle, etc but this cooks food ,they come in ,alloy. stainless steel,copper,brass,ive seen sizes from 2 litre capacity to about 6 litre but theres probably bigger. you put sticks twigs etc from the bottom as well as the top.
