I've smoked fish, but never crab cakes. I seasoned up some tilapia fillets, put together some MD crab cakes, and cooked everything indirectly on the charcoal grill with some soaked hickory chips for added flavor. I cooked the fish for about 15 minutes and the crab cakes for 25 minutes. Turned out great. The smoke on the crab cakes was better than I had hoped. A little homemade tarter sauce and a few black and tans and I was in heaven. Mike C.
