We were invited to a holiday dinner on the only nice day during the entire Spring Festival. Lucky us! Our region is known for its seafood, and that's what we had. There were snails, clams, squids, steamed fishes, shrimp, crab, oysters, and type of shrimp I'd never seen before. The shell was very thick and thorny. It looked like a giant, nasty tater bug. The boss's mom showed me what to do with this monstrosity. First you bent it back and forth, taking care not to get poked by the thorns. Eventually the meat loosened up enough to pry out. You were then rewarded with a cross between lobster and crab, well worth the pokes from the thorns! Grandma ate about half a dozen of these huge things, about 20% of her weight, I think.
