Sliced thin, but only partway through the spud, Hasselback potatoes are packed with flavor. Prepare perfect potatoes at home with the Charcoal Companion Hasselback Potato Slicing Rack. The rack helps you achieve perfectly-spaced cuts without accidentally slicing through the entire potato. Just place your potato on the wooden dish, push onto the nails to hold it in place and start cutting through the stainless steel guide wires. When done, slide the guide off and grill or bake to perfection. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Tools & Utensils.
