So easy, great presentation and twist to fish. I've used other 3/4"-1" thick fish and recommend marinating the full 4 hours if possible. Recipe courtesy of Giada, Everyday Italian.
Pour marinade into a small heavy saucepan and bring to a boil and then back to a simmer for about 15 mins., stirring often.
08While sauce is simmering, broil the fish until they are just cooked through and carmelized on top, about 12 minutes (Watch last few minutes that you're not too close to the broiler and fish is burning).
09In small pan, sauce will thicken similar to a steak sauce. Spoon off any excess oil if preferred.
10Transfer fillets to plates, drizzle sauce lightly on top just for presentation to keep the eye appeal of the carmelization and then spoon more sauce around the fish. Serve.
