On a cold December day in New York, I took the 6 train down from the Upper East Side to the Astor Place stop with porchetta on my mind. No, not Sara Jenkins’ glorious Porchetta sandwich served at her sandwich spot so devoted to porchetta it’s called, well, Porchetta. This time I was headed to Il Buco Alimentari e Vineria to try a porchetta sandwich that made a bit of a splash when it first appeared a year or two ago. Now the New York food media has moved on, as it tends to do, and that sandwich continues to be served with slightly less fanfare. I knew I had to give it a try before it disappeared entirely.
