Katz’s was famous before “Harry met Sally,” because as America’s oldest deli, they’ve made the best pastrami in the world since 1888. The journey of one of the most delicious sandwiches on Earth starts with tough beef belly that gets heavily salted, cured for two to three weeks and then rubbed with pepper, onion, garlic and coriander. From there, it gets smoked and boiled before getting tucked into a steamer behind the counter. The cutters are expert in slicing and know how to remove the pastrami's inedible membrane of silver skin and slice the meat thinly against the grain, which has a meaningful impact on the structure and texture of the finished stack. The result is pastrami that is beautifully colored, tender and delicious like no other sliced meat on Earth.
