Remove the crab from the refrigerator or ice bath. If very cold, you will see little movement.
Flip back the shell to expose the gills.
Pull away the gills and discard. Repeat the procedure on the other side of the shell.
Turn the crab to expose its underside. Pull back the apron.
Twist the apron and pull it away from the crab’s body. Discard.
Using kitchen shears or a knife, cut away the eyes and mouth.
The crab is now ready to be fried, sautéed, broiled or grilled.
