I have not featured many fish recipes here on Just Hungry. This is because at the moment I live in a landlocked country, where sea fish must be shipped in, and is expensive to boot. When I do buy some fish, I savor it as a treat. (I may be preparing myself for something that all fish eating people might have to endure soon, given the problems of overfishing.)
This is a classic miso marinade with a spicy twist. Instead of using just miso, I've added a little bit of kochujang, spicy Korean bean paste. I've used cod for this, but you could use any firm, flaky white fish instead - or even an oily fish such as salmon or swordfish. The pieces of fish should have a certain thickness, so thin fish like flounder won't do.
