This male crab has a "tab" that looks like the 'Washington Monument', a female
crab has a tab that looks like the US Capitol.
Pull the tab off, by pulling the hard shell away from the crab. Crack the
crab cavity in two. Pull the legs off or not, your choice. Scrape out the
"mustard", you can eat it if you want to or discard it.
The mustard is an acquired taste, either you love it or it completely grosses
you out. Don't eat the lungs aka "devils fingers". Pull the cartilage away
and scavenge with your finger tips to pull the crab lumps out.
Dip the lump crab meat in drawn butter, or --add more Old Bay, or...dip in
white vinegar or just eat the lumps plain. It's heaven! Enjoy! A note, dipping
in vinegar actually brings out the sweetness of the crab meat!
Newbies use mallets, nut crackers or knives and wear bibs. Marylanders only
use their hands and fingers and sometimes the bottom of a Bud bottle to hammer
on the claws.
