An article of cookware is fabricated by a combination of a deep drawing a metal sheet or laminate to form a fluid retaining preform and then using an impact bonding process to attach a medallion to the outside bottom surface of preform. In another aspect, the impact bonding process alternatively provides a means to achieve a slightly concave exterior bottom surface, while maintaining a substantially flat and/or slightly concave interior bottom surface to minimize the use of cooking oil. |
