Not merely for frying, the grill pan will add crispiness and juicy goodness to anything you grill as well.
Iwate has a centuries-long tradition of ironware production. The iron is molten at more than 1,500 degrees Celsius, the casts are made entirely of recycled materials, and everything important is done the same way it's been done for hundreds of years. Iwachu's Nanbu *tekki* (Nanbu ironware) is known for its application of this tradition to contemporary needs.
When cooking meat, the transfer of heat sears the exterior surface of the meat quickly, sealing the meat's natural juices. It is no coincidence that Nanbu *tekki* is used for the grill tops that adorn many of Japan's best steak restaurants.
