Abstract
Abstract An improved scrap block for use with commercial food service equipment. An upstanding lip extends inwardly along a portion of the upper edge of the block to allow rapid removal of jelled liquids and food particles from dishware. The lower engagement wall has a circular bead detent around its outer surface to insure that the block will not be knocked out of position. The block has an annular skirt covering the receiving hole, preventing drippings getting therein.
