A wafer half-shell is described and has a mouth delimited by at least one annular surface (8) and one or more side walls (10), in which the mouth surface (8) and the surfaces (18, 20) of the side wall (10) have a substantially smooth surface finish, and the outer surface (20) of the side wall (10) has a porous, continuous or discontinuous region (22) which extends peripherally and is receded relative to the mouth surface (8) of the half-shell, resulting from the cutting of a radial wall (6) connected to the side wall (10) of the half-shell in a receded position relative to the annular surface (8) defining the mouth of the half-shell. The half-shell is useful particularly for the production of a food product comprising a pair of half-shells fitted together mouth to mouth and including a mass of liquid filling.
