A brand of breakfast cereal, introduced by Kellogg's in 1983. It was created specifically to compete with Ralston Purina's Chex family of cereals. Its box touts its unique composition of "Crispy rice on one side, crunchy corn on the other. " The cereal itself is in a hexagon shape. The two sides are made in a lattice pattern and connected only at the edges; the centre is open allowing for greater crunch. Crispix is kosher/parve.
