From the net.....
Karen - Hi! I saw this done on bizzare foods phuket thailand. I am thai as well and had never encountered this crustacean/ parasite/ flea….whatever this thing may be…i live in northern california and decided to harvest some from halfmoon bay and see what this hype is about. Harvesting was simple.. I harvest about 50+ crabs.. All female including egg sack. I harvested the second week of august (i guess thats when all crabs lay their eggs) they were sooooo cuuuute….but I knew that they had met their maker..

feelings aside…cleaning was a bit tedious. I didnt remove anything from the crab. Just 2-3 soak in cold water to remove the sand. Towel dried well..dusted with flour seasoned in garlic salt. Deep fried at 375° for about 5 mins or until they float.
Result: best damn crustacean I have ever had!! The most cleanest taste. Its like popcorn shrimp/crab/and crawfish in one!! Minus the poop and brain matter!! If you have never tried these lil guys…i highly recommend it..this will be the next thing sold at our local fish market!! Gaurantees!
