SLOTDOG® has a grid of stainless steel blades that create perfect criss-cross slots in your hot dog. The slots expand while cooking. Smoke, Grill Flavor, Seasonings and Rubs penetrate deeper. Juices caramelize on the edges for a crispy bite. Plus, the slots grab hold of your toppings with a Kung-Fu grip! And, it's Dishwasher Safe.
