Thank you to everyone for these fine suggestions!
I forgot to thaw the fish, and so it is still in the freezer, perhaps tomorrow.
The Cod Brandade, which I had never heard of, sounds fabulous, but one cup of heavy cream to a half a pound of fish? Yow.
I think I need to eat the Korean spicy fish stew in a restaurant first, to get a sense of what I am aiming for at home! Does Hae Woon Dae serve this, anyone know? (Just had carryout bi bim bap from there tonight, could have had the fish if I had read this in time!)
The Moroccan tagine sounds like exactly what I am looking for, I looked at the one that was linked and googled some more,will definitely give this a try. Couldn't google it though until I knew it existed, which I didn't until it was suggested here. (Which raised the question, what other countries have fabulous fish stews that I need to know about so that I can google a recipe? I'm not in the habit of ordering fish stew when I eat out; obviously, that's what I need to do.)
The original Spanish version that I had and then copied at home did have homemade chorizo, which was very yummy. (I sadly subbed chicken sausage.) I believe it was a salt cod recipe, but my sister-in-law used fresh (or frozen and thawed, but anyhow, unsalted).
The OP by the way is not he, but rather she. Either that or deeply incognito.
