How to Prepare Green Crabs for Making Stock

You can smash, crush or puree whole crabs, add water and make your stock or broth this way OR you can prepare the crabs the more tedious way like I do! Believe me, if I have a choice I prefer to do things the fastest and easiest way possible. It may sound time-consuming but I find that it is a better process to get the most out of my crabs. Part of my process is to clean the crabs by removing mud and sand, even though ingesting a little on occasion is not harmful to most people. The other essential part is the removal of the yellow-orange roe and/or crab mustard, if there is any. The crab mustard is the hepatopancreas, a filtering organ found in crabs and lobsters. These innards may sound toxic to ingest and probably are but for some people they are a delicacy. Eat with moderation if you are healthy and avoid if you are not.

My process of cleaning the hard-shell crabs for making stock is similar to preparing the soft-shell ones. The difference is removing the entire carapace in order to get to the yellow-orange matter and keeping the pointy legs intact. The hard-shell crabs are much stronger and faster than the soft-shell ones so you need to work a little faster and apply some pressure when removing the carapace. I remove these parts with my fingers but you can use scissors with pointy tips--carapace (dorsal shell), the gills on each side of the body, and the V-shaped apron on the abdomen. Scoop out the yellow-orange innards and reserve it in a separate bowl. For me, the best way to remove the most of this innards is to use a pointy flat knife. They are found in the interior of the carapace and on the middle of the body just underneath the carapace. Once these tasks are complete, rub the crabs with a little salt, rinse the prepared crabs in cold water, strain and place them in a clean bowl or pot to be used. Save the scooped out roe and crab mustard and keep them refrigerated until ready to use.

Helpful Hints:

*If you are planning on crushing the crabs then you may keep the point legs intact to save time. Removing them makes no difference in your stock.
*In my family we clean the prepared seafood with a salt rub (about 2 teaspoons to 1 tablespoon) and then wash with cold water several times to rinse off the salt. You can also do the same by using vinegar (about 2-3 tablespoons) to wash then rinse with cold water immediately. Do not allow the seafood to soak in the salt or vinegar.
*When preparing the crabs you may want to wear gloves to prevent injury. I find that wearing 2 layers of the exam gloves to be most helpful when cleaning the crabs. You may purchase these exam gloves at your local pharmacy store or online.

Green Crab Ice Cream

The best part about making my own ice cream is that I can control the amount of sugar that goes in it and I can add just about anything that...
