In years past, we always cleaned the crab before bringing them aboard, cooked them, and then refrigerated or froze it. Because they are ubiquitous, we used Zip-lock bags for storage.
So this year, Jane is trying something different. First, she is picking all the meat. Tedious work, but realistically, most of the crab we froze last year ended up getting picked anyway to make crab cakes. So she is just doing this up front.
Bonus: out of the shell, the crab takes up a lot less space in the freezer!
And of course, none of this applies to the crab which we eat on board, fresh from the sea!
