Chef John's Copycat McRib Sandwich

"I tip my cap to a certain fast food franchise for coming up with the idea for a boneless baby back rib sandwich," says Chef John. "The only downside being that they use about 60 mystery ingredients — ribs not necessarily being one of them. That's why you should try this easy homemade version with real ribs; simply bake, chill, cut, sauce, finish on the grill, and voilà! One of the best sandwiches I've ever had."
