You can cook lots of different things in. It. I bought the accessories kit online for it. Came with a kabob rack, rib hooks, meat hooks and 2 racks for chicken legs & wings. I also got another basket insert to go inside the one that comes with it so I can cook 2 chickens at a time. As long as your paying attention to your heat I dont see why you couldnt do crab! This fryer is worth every penny.
