Balsamic Onion Marmalade

In La Jolla, California, it was the Cassius Clay at The Sandwich Club. In Evanston, Illinois, it was the Pesto Chicken at Rollin’ to Go. It seems that I’ve come to associate an “it” sandwich with every city I’ve ever lived in. And New York is no different.

There’s pastrami on rye at Katz’s, or Le Croque Monsieur at Bistro Bagatelle. But at the absolute top of my star sandwich list is the roasted turkey sandwich at Tom Colicchio’s ‘wichcraft. Piled atop a toasted ciabatta roll are thick slices of warmed turkey breast, sliced avocado, crispy bacon, aioli, and the final touch that makes this sandwich the ultimate New York City ‘wich—balsamic onion marmalade.

Heat vegetable oil in a large skillet over medium heat for 2 minutes.
