America is a land of sandwiches: We love the classics and can be fiercely protective of the way they're built. Jeff respects the great sandwiches too, but that doesn't mean he's not going to tinker from time to time. So in this episode, he heads to Gramwich, where chef Merlin Verrier has been tweaking the mainstays of the American sandwich pantheon for years. The visit with Merlin inspires Jeff to reimagine the venerable BLT using pancetta instead of bacon and subbing avocado crema for mayo. Then he dishes up a Sloppy Joe that gets its flavor from the markets of central Mexican, but brings it back stateside thanks to a tangle of crisp onion rings. America's never tasted better!
