As far as I can tell from the tortured syntax, the recipie is essentially a sauce poured over sautee'd shrimp.
If that's the case, you can pour it over anything your little heart desires, from cubed, battered and fried haddock to lobster.
Hell, you could drizzle it over grilled trout, if you wanted. The flavor in this dish isn't in the shrimp, it's in the sauce. Knock yourself out.
Also, try using a blood orange instead of a regular orange.
Also also Trip0, if you start with 1 cup of OJ, I think you're supposed to reduce until you get 1/4 cup of OJ.
