The bottom row of triangles (26) are folded in and joined together side by side by complementary fastening means (20, 22) and the triangles (16, 18) of the intermediate row are folded around to form a ring, with complementary fastening means (20, 22) on the endmost members being secured. Truncated isosceles triangles (24) may be joined by the score lines (14) along the top edge of the central strip with complementary means (20, 22) attaching them together side by side to complete and reinforce the core with a central opening (29) in the top. A stem (32) extends down through the central opening (29) and is secured to the interior of the core (30) to enable the core (30) to be rocked. A cluster of three balls (38) is secured to each of the triangular panels (16, 18, 26) in the central and bottom rows to knead and indent a dough ball as it is rocked over them.
