I have only made this with fresh crab meat, hand-picked and packaged. This stuff is pre-cooked or steamed and found in the refrigerated bins in front of the fish section at your supermarket. You can eat it right out of the tub, just needs some heating through. "Jumbo lump" is my favorite, but at 1/3 of the price, the claw meat variety is also delicious. *I have not tried this with tinned/canned crab meat.*
