Abstract: A rippled wafer (90) formed of a convoluted wafer ribbon (80), the rippled wafer (90) having an average of at least 12 turns/cm2, wherein a turn is a change in direction of the wafer ribbon (80) of at least 45°, and a confectionery product comprising such a wafer. Also a confectionery product comprising a rippled wafer (90) formed of a convoluted wafer ribbon (80), wherein the turns are substantially uniformly distributed across the cross section of the rippled wafer, where a turn is a change in direction of the wafer ribbon of at least 45°, and a confectionery product comprising a three-dimensional rippled wafer (90) formed in a single step.
