I'm planning to wrap a whole salmon with herbs and lemon with banana leaves, then wrap the whole thing in foil, and roast/steam the beast over an open flame. This will be done sometime in June at a friend's house.
I've never used nor purchased fresh banana leaves. I imagine they'd be avaliable at Mexican or Southeast Asian markets, but which ones? Any suggestions of good places to find a ready supply? (I'm in Pasadena, and my friend is in Huntington Beach, so I'm prepared to purchase them in or near one area or the other.) How much should I buy? Is one leafy layer around the salmon enough, or should it be multiple layers? Any tips on cleaning and prepping them?
