The McGriddle, a heavy, sweaty, floppy little thing, is somewhat off-putting at first.

"Is this kosher?" I asked the clerk, stuffing the paper bag into my knapsack.

She stared at me blankly.

"No, I'm sure it's fine," I said. Of course, the McGriddle is so far from kosher that if you listen carefully while you chew, you can hear the tiny voices of ancient, highly regarded rabbis yelling at you from beyond the grave.
