There are many Paula Deen fans on Recipezaar. This is her recipe that was on foodnetwork.com.
The recipe makes alot of BBQ sauce. Way more than you'll need unless you plan to drench the fish in the sauce. I cut the sauce recipe down to 1/4th of the printed amounts and still came up with close to 1 cup of sauce, which gave me alot of leftover sauce.
Season the fillet in step 3 using recipe #57340
The recipe calls for 1 lime, juiced but the instructions never mention it. Since it is the last ingredient on the list, I am assuming that the lime juice is sprinkled on the finished fish fillet.
I think the BBQ sauce benefits from being made at least earlier in the day or maybe even the day before. I didn't particularly care for the flavor of the sauce when I finished making it but after it had set all day and was put on the fish, it was good.
