Frozen pollock is called dongtae (동태) in Korean. You can find frozen pollock fillets in the frozen food section of Korean markets. They are sold with the skin and bones removed, making it easy to prepare Korean fish pancakes at home.
To make dongtaejeon, let the fillets partially thaw until they are still firm and slightly icy, then slice them thinly. Season the slices with salt and pepper, coat them lightly in flour, dip them in beaten egg, and pan fry. Because the slices are thin, they cook quickly.
See my dongtaejeon recipe for the full instructions and step-by-step photos.
