Appetizing stores, of course, are New York. They’re an integral part of the city’s unique culinary mosaic and first appeared en masse with the huge wave of Jewish immigrants from Eastern Europe in the early 1900s. According to Jewish kosher dietary law, meat and dairy can’t be sold or eaten together. As a result, appetizing stores and delis were created to serve complementary and distinct purposes: delis served meat; “appys” sold dairy, fish, and food that generally goes with bagels -- cured, smoked, and pickled edibles, salads, and spreads. By the 1930s, 500 appys were open in New York City. Five hundred! In 2015, that’s roughly the number of Starbucks and McDonald’s combined. Today, we can count the appetizing stores that still exist on two hands. Once part of every neighborhood, they slowly receded from the city’s landscape in the late 20th century due to a mix of factors, though now there are signs of revival.
