Yes you can!
I spotted this at a supermarket recently. Yes those are little crabs - fried to a crisp, with shell on. Since I had already broken a filling just the day before, I did not buy any so I can’t tell you what they taste like (crabby and splintery?)
It just goes to show how there is a market for probably just about anything you can think of. Or can’t yet imagine!
But – how many different crab snacks does the world need? How many tonnes of this stuff is shipped around the world daily?
