More than 28,000 food buyers from around the world, including thousands from U.S. retail and restaurant companies, will descend on New York City this week, to taste the latest sweet treats, savory snacks, spices, sauces, olive oils and other new flavors at the Specialty Food Association’s Summer Fancy Food Show. The sprawling halls of the sold-out show will boast more than 2,700 food makers, importers and culinary entrepreneurs representing countries from Argentina to Wales. It’s slated to be the biggest turnout since the show began in 1955.
