As an avid crab lover, for how to deal with crabs I think I'm still considered more of a right to speak. Next, I'll summarize a few of the steps I take to deal with crabs, so I hope this helps you!
First I would use scissors or chopsticks to poke through the crab's mouth, followed by breaking its pincers.
Then turn the crab over so he's showing his white belly, lift it off and cut off his butt.
And then I would brush the surface of the crab with a brush. As a reminder, make sure you brush it because its shell is really dirty.
Next, you can open the shell, remove the gills, mouth and eyes, and most importantly, the stomach and heart must be removed, because this is a cold crab, so for the sake of our health, it is better to be cautious.
Such a crab will kill a good finally can start the pot waiting to eat fresh crab!
