1. Stun live blue crab by placing in ice water for 5 minutes.
2. Grasp crab by its legs and under top shell spine (stunned and can be handled bare handed).
3. Pry off the top shell using the shell's spine for leverage.
4. Flip crab over and remove the apron.
5. Using high pressure water, spray out the entrails.
6. Using thumb, twist off the mouth parts.
7. Remove spongy gills from both halves.
8. Cleaned and ready to cook.
Create the crab mash, customize to your liking: Take your large pot, put about 2 inches of water in the bottom. Add olive oil. Add freshly minced garlic. Add season-all salt, ground red pepper, crushed red pepper, and salt and pepper. Mix well, then warm.
Take the cleaned crabs and dip them in the mash and set aside. Sprinkle crabs with coarse garlic with parsley, also add some ground red pepper and any other ingredients you like. (Williecrab recommends adding some Italian bread crumbs, grated parmesan cheese, and grated Romano cheese to the water and sprinkled directly on the crabs before cooking them. The cheeses melt on the bodies and the spicy bread crumbs puff up and splatter on the crabs in the steam.)
Cover pot and bring the mash to a hard boil. With the mash boiling, lift the lid and dump in about 15 to 20 cleaned crabs (depending on the size of your pot). Put the lid on and oil-steam them for 12 minutes. Make sure there is plenty of room in the pot for the steam to circulate little drops of olive oil on the seasoned bodies of the crabs.
After 12 minutes the claws and legs should turn bright orange. Remove crabs and test a claw. If the meat slides out and is juicy, you got it! If the meat is stuck in the claw, you are cooking them a little too long. If you do not like the crabs getting mushy on the bottom, put a platform at the bottom to keep the crabs out of the mash.
If you really like garlic, put some freshly minced garlic right in the bodies before you steam. If you've got time, try pre-cracking the claws before steaming. If you do it right, you won't need a wooden hammer to break open the claws. The trick is to cook the crabs so that the spices "melt" into the meat and the bodies of the crabs have an olive oil sheen on them. When the crabs come out of the pot, sprinkle with freshly grated parmesan and Romano cheese, with just a tad of butter, which melts into the meat making an incredible.
