After watching a episode of Bizarre Foods from Thailand I saw these folks were consuming mole crabs aka sand fleas. In the Treasure Coast we have them in abundance and if you have the right equipment and a little technique gathering a few is a cinch. These little crustaceans are typically used as bait for tasty surf zone fish such as pompano, whiting and the like. Turns out they are not just pompano candy but a tasty snack for anyone that enjoys seafood. Cleaning them is a matter of running them under cold water in a collander and removing a small appendage they use to dig into the sand. First you twist the little tail off and give them a gentle squeeze to coax out any remaining grit (ie poop) they have in their bodies. Rinse one more time then dredge them in a combination of corn starch, salt and a little powdered garlic. You can add other spices to the mix but our first batch we went minimalist to preserve the authentic taste of the "fleas". I used a deep fryer set to the highest temp setting. Wait till they float, remove and allow them to cool some. Dip in any sauce you like and crunch and munch. We set out regular cocktail sauce and a grated ginger thai style sauce.
Don't worry about the shell and feet when fried they become very crunchy like "tater" chips and the taste of the crab meat and roe is what you taste. Being reduced to eating the bait might sometimes be seen as the sign of a bad fisherman but at least your not hungry. Enjoy!
