2010 was a big year for Fany Gerson. A native of Mexico City and a former pastry chef at Eleven Madison Park, she spent the spring and summer launching her business, La Newyorkina, which sells traditional Mexican ice pops and sweets. But as winter approached, business began to slow down, and a good friend of hers suggested that they open a doughnut shop together.Fany was skeptical at first—“Bed-Stuy didn’t seem like the obvious place for gourmet doughnuts”—but in spite of her reservations, she accepted the job. After long discussions with her business partner about textures and flavors, Fany set out to create the perfect old-fashioned doughnut, thick and hearty, but also light. “We wanted a doughnut that would taste good naked,” she told me “and we knew it was all about the dough, hence the name.” Finally, after endless tweaking and experimenting, Fany hit on the perfect recipe, and three weeks later, Dough opened its doors in Brooklyn.It was the beginning of a wonderful partnership. Throughout the fall and winter, Fany devoted most of her attention to Dough; as the weather grew warmer and doughnut sales declined, she had time to develop new flavors and recipes for La Newyorkina. But it has not always been easy to balance the two businesses, especially since Dough’s second location opened in the fall of 2014. “That first summer,” Fany recalled, “the hot weather unexpectedly affected the doughnuts, and I had to adjust my recipe last-minute and work on La Newyorkina at the same time.” She smiled, and added, “I don’t get a lot of sleep.”But in spite of the difficulties, it is obvious that Fany loves what she does. She gave me a fascinating tour of Dough’s kitchen, enthusiastically pointing out where the dough rises and how the doughnuts are fried, about one minute on each side. “Most places make their doughnuts in the morning,” Fany explained, “but we take it a step further. Our doughnuts are fresh and warm whenever you come in.” Once the doughnuts are fried, they are ready for the final touch—the glaze.I was eager to ask Fany about this stage of the process, since Dough is known for its exotic flavors—some of its best sellers include hibiscus, mocha almond, and dulce de leche. “Inspiration is everywhere,” Fany told me, “but a lot of my flavors come from my memories of Mexico.” She invented the hibiscus flavor, for example, on a hot day when she was craving the refreshing hibiscus water that she used to drink back at home. “We needed a colorful doughnut,” she told me, “but I didn’t want to use coloring. And it occurred to me that hibiscus has a beautiful natural color.”Some of Fany’s flavors have become so popular that customers complain if she takes them off the menu. “We have a few flavors that rotate, but not many,” she told me. “We have to give the people what they want, but we also try to keep it interesting.” Some of Dough’s best-selling staples include salted chocolate caramel, café au lait, and nutella, although Fany’s personal favorite is the cinnamon sugar. “I also like the tart flavors, like passion fruit and tropical chile,” she told me. “The glaze is a nice contrast to the richness of the doughnut.”I was surprised to learn that, in addition to producing hundreds or even thousands of doughnuts each day, Dough runs a wholesale operation at night, selling doughnuts to nearby coffee shops and supermarkets. To keep the business running smoothly both during the day and at night, Fany estimates that Dough employs thirty or forty employees total.Dough has been hugely successful, and Fany told me that they will soon be opening another location in Manhattan. “It’s hard,” she told me, “I’d like to see the business grow, but I’m hesitant to do franchises in other cities.” Instead, she prefers to keep Dough personal, developing new products and flavors and expanding on a smaller scale. “We’re trying new things every day,” she told me, “and we’re growing organically.”After the tour, Fany led me out to Dough’s front counter. “Would you like to try one?” she asked, and after a moment of deliberation, I chose the dulce de leche doughnut. The smooth caramel flavor of the glaze paired perfectly with the crunchy slivered almonds on top, but the best part, as I expected, was biting into the soft, airy dough, still warm from the oven.
