It's Dungeness crab season in California! I've been buying these yummy critters for $2.99 per pound at Sun Fat Seafood. Great prices on cheap crab are being found all over San Francisco at places like Manila Oriental Market, Chinatown, and Clement Street. If you've felt intimidated about cooking and cleaning your own Dungeness, don't. I'll talk you through it here.
First, always select Dungeness that are feisty and active. They should come out of the tank fighting. Never buy crabs that come out of the tank with no fight in them. Sniff them. They should smell clean, like the ocean. If you detect any ammonia odor, do not buy. Cook the crabs the day you buy them, preferably within a few hours of purchase. They will not last long outside of the saltwater tank, so this is not something you can keep in your refrigerator overnight. When you get home, put the crabs in your refrigerator. This will get them sleepy and sluggish and makes them easier for you to handle them.
I prefer to steam my crabs instead of boiling them, as I feel the meat comes out more tender and flavorful this way and is not so waterlogged from the cooking water. I have a huge cooking pot with a steamer rack that I bought for $39 at the Giant Value store on Mission Street in San Francisco. Many of the el cheapo stores on Mission Street sell these large aluminum cookpots with racks. They are used for steaming tamales, but I've found that they work well for cooking lobster, crab, and other large amounts of shellfish. Amazon.com also sells them, such as this one here.
Calculate your cooking time as 7 minutes per pound. If you're cooking more than one crab, calculate by average crab weight, not total crab weight. It is always better to under cook, because you can then cook a little more, but you cannot undo an overcooked, rubbery crab. Fill your steamer with water up to the rack and bring to a boil. Add your crabs, close the lid, and wait. They will turn bright orange - here's why! Once they are cooked, stop the cooking process by putting them in a waiting ice bath. Once chilled, you can easily handle them. The meat inside should be opaque and white, not translucent. If I'm planning to cook the crab in a stir-fry or roast them, I'll usually under cook them during the steaming, and then crack them, and finish the cooking.
To clean them, follow these steps:
1. Flip the crab over and remove the "apron" and the mouthpieces from the bottom of the apron.
2. Remove the legs and place in a bowl.
3. Stick your finger in the hole where the mouthpieces were and lift the crab body away from the shell (carapace.) Toss the carapace. However, if you're making crab stock, save the carapace and clean out the entrails.
4. The greenish/yellow stuff is the liver. You can eat it if you want. The purple stuff is not edible, toss it. The grayish, pointy-shaped things on either side of the crab body are the gills. Remove them. Remove the two J-shaped parts at the opposite end of the crab's mouth.
5. Rinse off the body to remove any foam or entrails. Add it to the bowl with the legs.
Now you're ready to crack away and eat them with butter, or use the claws, legs, and body in other recipes!

I have to say, i prefer buying mine cooked and cleaned. I'm lazy, and creeped out by the thought of biking with what amounts to a giant spider in my basket.
i love dungeness crab! I usually steam it with a paste made out of ginger, garlic and oyster sauce cooked down.
To prep the crab, while alive, i have it flipped upside down on the cutting board. Then with a cleaver hack straight down the middle, careful not to pierce the top shell. The crab should be dead by now. Then rip off each half from the top shell, remove the tail, gills and any yucky stuff inside. Then cut in between each leg, so each piece has a leg and some of the body meat. Rearrange back on plate, slap on the paste and steam. 15-20mins for a 2 pounder. Delicious
Nice demo! I moved to Maryland a few years ago, and you're not allowed to live here without knowing how to pick crabs. It looks intimidating when you're faced with a Old Bay-encrusted blue crab specimen on your table but it's really not too bad! I'm still a little worried that I'll eat the 'devil' (gills) on accident though.
Though I've never cooked one myself, my uncle has had his own crab pots in Puget Sound for as long as I can remember. He always boils them in *very* salty water, like a couple handfuls (for my hands that's probably be three) of salt per crab. Us four cousins could easily demolish two or three in no time flat.
My parents just bought a couple, cooked, from a grocery store here and it was obvious there wasn't enough salt in the water.
If you like sweet seafood, like lobster, then go for the steaming. But if you prefer it tasting like the sea, like oysters, boil them with tons of salt.
I'm a vegetarian and it's just for ethical reasons... normally the sight or smell of meat doesn't gross me out (desensitized to it as a kid, I guess?)... but these pictures and descriptions really do gross me out. Sticking your fingers in holes to rip off body parts of a giant insect doesn't sound too appealing, especially when body parts can only be referred to vaguely as "yellow stuff" or "purple stuff". Think what you want about vegetarian food, but it's rare you find anything vegetarian that can gross a person out.
i use the backend of a heavy knife to crack the legs also, makes it easier to eat.
Pickles, Corby, pickles really gross me out. If Kathryn had said to pull out the liver, I wouldn't have a clue what she is talking about, but the "greenish/yellow" stuff - that I can identify.
Yep, I was out after Step 1.
Yummy! I understand vegetarians being grossed out by this. For those of us who eat meat and fish, it's probably good to get down and dirty with it like this, to understand where the delicious crab is coming from, rather than just buying lump crab in a carton.
@maddhatter: Is it just pickled cucumbers or is it any kind of pickle? Pickled beets? Is it just pickles that are preserved in brine or do you also get grossed out by Indian-style pickles preserved in oil?
I think anyone that eats it should know how to cook it. Thanks for the demo from a huge Dungeness fan in the Northwest.
I absolutely love Dungeness crabs. Nothing in the crustacean world comes close to the delicate flavor and soft texture of the Dungeness. Really, cleaning a crab is quite easy once you know how to separate the legs and body sections. A pair of kitchen shears is handy for cutting along side the legs and removing whole sections of meat. Crab Louis! Crab Cassarole !
nice illustration of how to prepare some delicious food! but for the record, crabs aren't insects. they're in the class crustacea (not insecta), just as we're in the class mammalia and birds are the aves.
@Corby: i've met a lot of people who get grossed out by various veggie foods. tofu, beans (fermented and otherwise), bananas...
Spaghetti squash grosses me out, but not as much as self-righteous vegetarians. Why bother to give us your POV, Corby?
I think blue crabs are superior to Dungeness, but all crabs are good.
@mrfaux: why bother? freedom of expression for a start. you're expressing your opinion, are you not? if so, don't ridicule others for doing the same.
opinions can be beautiful things and i'd like to learn more of them. i know you like blue crabs more than others and aren't into spaghetti squash. those are nice. i also like knowing that corby is an ethical vegetarian.
@Corby - cucumber pickles. I'm not a big fan of most pickles (homemade mango pickle being the exception), but I cannot stand cucumber pickles.
Corby - Fermented bean curd grosses me out. Nothing like biting into something that looks like it came from the bottom of a trash bin - yum!
As for the crab - I'm out too. I'm not vegetarian but I am very squeemish...I can't eat anything that started by looking back at me (crayfish, smoked chubs, whole roast pig etc). Kudos to those of you who can though - you'll have better quality control over the cooking process.
