Sculpin makes an excellent soup. My Sicilian Grandmother's (Mema) skipuni (sculpin) soup:
sculpin (or any other small rockfish) cut in chunks (head too!)
garlic (however much you like)
onion, cut in chunks
potato, in chunks of course
parsley, lots!
lemon, I'd say one lemon per fish
extra virgin olive oil
salt and pepper
Cover potato, onion, garlic with water (just over top of potatoes). Add salt and pepper to taste. Cook till potatoes almost done, add sculpin. Cook till fish is done. Just before pulling out of pot to eat, add chopped parsley, drizzle olive oil to taste, squeeze fresh lemon over. Get some good french bread. I add more olive oil to fish chunks in my bowl.
Pretty simple, but very good!
