So yesterday I decided I was going to purchase some live blue crab from a local seafood store that I go to very often. I see them all the time so I decided to get a dozen. Lets just say I had no clue what I was getting in to. I decided I was going to just try and do a basic crab boil with corn, red new potatoes, kelbasa, etc. First off, I wasnt sure if I should clean them first or boil them and then clean'em. The crab were about 4 to 5 inches big and the flap on the bottom was in the shape of a rocket ( narrow). Long story short I had boiled them for around 6 min and then cooled them down. I could get little to no meat from the body. The meat in the claws had dark greenish brownish color on the outside of the claw meat.. It didnt taste very good. kind of muddy. I have heard how good blue crabs can be but it was a lot of mess and work for nothin. Whats the secret to cleaning them? Also I didnt know what I should do with the bodys of crab that I have cooked but not cleaned, so I froze the bodys.
