You can buy cooked crab meat at the local fish markets or supermarket. Alternatively, buy fresh crabs and cook them (blue swimmer crabs are good). To tell if crabs are meaty, look at the claws; if they are pointy and sharp it means they have a new shell and don’t have much meat. If the claws are rounded, they have an older shell and will have more meat.
