ABSTRACT:
A layered cooking vessel has a plurality of nested metal layers stacked from a highest one to a lowest one. Each one of the layers above the lowest one has a border folded downwardly to interlock with the next lower one of the layers. Each one of the layers above the lowest one has on its border an annular score dividing that one of the layers into a removable strip and a central bed. This removable strip is removable to reduce the size of the border to prevent interlocking with the next lower one of the layers. Thus successive ones of the layers can be removed. Instead of the scoring, the border can be made flexible to allow manual extension and lifting of the border to remove it from the lower ones of the layers without tearing.
