A culinary vessel is made from two sheets of different metals or alloys laminated together and stamped to form a vessel having a bottom and a side wall. The bottom incorporates small stamped cavities such that the cavities formed in the outer sheet enter complementary cavities formed in the inner sheet. This strengthens the bond between the two sheets.

[ There is claimed:] [1.] Method of manufacturing a culinary vessel from a disk made of two sheets of different metals or alloys laminated together and pressed to form a bottom and a side wall, both inner and outer sheets being in direct contact with one another over their entire surface, the method comprising: cold stamping said disk in the area corresponding to the outside bottom of said vessel to form small cavities which are sufficiently deep to form protuberances on the outer sheet in said area and to create complementary cavities in the inner sheet in which engage the protuberances stamped into the outer sheet; and thereafter pressing said disk to form said vessel.
