Edible QR codes at North End restaurant

William McAdoo reports on Jose Duarte's experiments with printing QR codes (think of them as bar codes for the smartphone set) on the plates at his Taranta in the North End. Why? Imagine scanning in the code and reading up on the seafood sitting in front of you:

The problem was: how to get it on the plate? His first attempt was with a rubber stamp, using edible squid ink. The squid ink proved a bit oily with traces of sandy grit that clogged the stamp. He then decided to actually screen print the code onto the plate using a more refined squid ink. This worked better.
