Abstract: A fanning plate for a baked potato provides an arched top surface to fan out the slices of a Hasselback potato during the seasoning and baking process, allowing the potato slices to crisp properly, as well as raised rims and endcaps to keep the seasonings contained and prevent a mess. Multiple plates may be easily stacked for compact storage.

Abstract: A cooking device having an arch to expand partially sliced food, such as food sliced by accordion or Hasselback techniques, during the cooking process. The device must comprise at least one arch with a convex section having a food expansion support. In a preferred consumer embodiment, the device is a pan insert with the required arch and food expanding support surface. A fanning plate for a baked potato also provides an arched top surface to fan out the slices of a Hasselback potato during the seasoning and baking process, allowing the potato slices to crisp properly. The fanning plate includes raised rims and endcaps to keep the seasoning contained and prevent a mess. Multiple plates may be used at once and when not in use may be stacked atop one another for storage.
