An unusual Japanese delicacy made even more unusual by the
fact that it is not raw. Prepared by eating a raw
jumbo shrimp (remember to suck out the yummy brains!),
dipping the remains in batter, and quickly deep-frying the result.
This magically transforms the chitinous shell into
a crunchy goodie that tastes very much like a potato chip,
except that you have to spit out the eyeballs (they harden
into glass beads), and most potato chips don't have long antennae or
dozens of little insect legs hiding in their mouths.
A (more) common variant is deep-fried unshelled little shrimp, kawaebi karaage, eaten
whole with a dab of mayonnaise, usually as an accompaniment to
beer. But they look much less scary when they're small...
(Incidentally, I've never seen deep-fried shrimp heads
on a menu by themselves; better izakaya will serve
the shrimp themselves as sashimi and then ask you
if you want to fry the remains.)
