    Abstract: The present invention relates to a culinary article (I) comprising a hollow metal cap (2) which comprises a bottom (211) and a side wall (212) rising from the bottom (211), said cap (2) having a concave inner face (21) suitable for receiving food and a convex outer face (25), said inner face (21) being coated with a coating (5) consisting in series, from the cap (2), of a hard underlayer (3) and a non-stick coating (4), the non-stick coating (4) including at least one layer comprising at least one fluorocarbon resin, alone or in a mixture with at least one thermostable bonding resin that can withstand at least 200° C., characterised in that the hard underlayer (3) is provided as a discontinuous layer, in that said hard underlayer (3) consists of one or more non-fluorinated polymeric materials selected from polyaryletherketones (P AEK) and mixtures thereof, optionally of inorganic hard fillers, optionally of conductive fillers and optionally less than 3% by weight of additives relative to the weight of said hard underlayer, and in that the average equivalent diameter of the pores in the hard underlayer (3) is greater than 5 11 m and in that the coating (5) has an overall porosity fraction greater than 8%.
