C. and including a glaze which melts essentially at these temperatures and that penetrates and bonds inside the pores (15) of the biscuit, and at least one substance that does not melt at the melting temperature of the glaze and which forms surface grains, or ovules (17) enclosed in the melted part (16) and anchored to the base of the biscuit.
