Cronut

The Cronut is a pastry created and trademarked in 2013 by the French pastry chef Dominique Ansel. It resembles a doughnut and is made from croissant-like dough filled with flavored cream and fried in grapeseed oil. In 2013, the French bakery owner Dominique Ansel created the pastry out of dough similar to that of a croissant (a pastry that he had been more familiar with) with flavored cream inside. It took Ansel two months to perfect the recipe. Ansel introduced the Cronut on May 10, 2013, at Dominique Ansel Bakery in New York's SoHo neighborhood. That night, a blogger from Grub Street, the online restaurant blog from New York magazine, reported on the new pastry. The post resulted in much interest and online circulation, and by the third day, a line of over 100 people had formed outside the shop to buy it.
