I am still learning in this area. I cook shrimp, tilapia, cat fish and crabs. I make Crab Tikkis ( Indian version of Crab cakes) all the time. WHen I used to cater, a favorite was a a rainbow trout marinated in a cashew ginger sauce. The trout is the covered in foil and baked. It is a very delicate fish and the cashew and ginger really complement the flavors
