My BIL doesn't like fish, so anything that tastes like fish is out, lol. Catfish - not a chance! The batter and frying cover up any possible flavor that cod might have, leaving an empy palate of delcious oily crunchy batter. That is what BIL wants. Maybe I could just throw the batter in the oil and give him that, lol.
After I typed this, I thought of pollack, but I wasn't sure, so thanks for that idea. I haven't seen it around, but I don't look farther than WF most often. I saw tilapia when I looked the other day...it's just not a tasty fish to me, but maybe cooked this way it would work. It was noted that perch could work, too. Walleye isn't always easy to find, or inexpensive, but tilapia and perch are. Neither have the meatiness of cod. Haddock does, but it's not necessarily less expensive.
I didn't see white, relatively tasteless fishes at H-mart. I haven't visited the place on Fulton, so maybve I'll head over there in the near future and see what they have. I am thinking of buying just one small piece of three or four species and trying them to see which reminds me most of the cod.
Thanks for all the ideas.
Oh, I looked online and saw hake recommended. But, I can't say I've ever seen hake aound here. Nor do I know its status in terms of sustainability.
