While most of her contemporaries were concerned with opening a restaurant, pastry chef Fany Gerson had another goal. "Most friends and colleagues I have in the industry had dreams of having their own business," she says. "Mine was to write a cookbook." The Mexico City native and Culinary Institute of America graduate did just that in 2010 with My Sweet Mexico, an ode to the sweet offerings of her upbringing. That same year, she debuted La Newyorkina at the Hester Street Fair, where she began selling a selection of paletas, Mexico's frozen, on-the-go treat that would become her calling card and the focus and namesake of her second book, released just one year later.
