The croissant as we know it began to take shape in the 19th century when August Zang, an Austrian artillery officer, opened the Boulangerie Viennoise in 1838 or 1839 at 92, rue de Richelieu in Paris. This bakery quickly became a favorite for Viennese specialties, including the kipferl and Vienna loaf, captivating the taste buds of Parisians and paving the way for the development of French viennoiserie—a term that would emerge later to describe these pastries. As the croissant gained popularity, it started appearing in culinary references. By the 1850s, the term "croissant" was already being used to describe these delightful pastries, regarded as luxury breads by 1853. The earliest known recipe resembling the modern croissant dates to 1905, highlighting the ongoing innovation in French baking. The technique for making croissants, particularly the use of laminated dough, has even earlier origins. In the late 17th century, recipes for puff pastry were documented, although this technique was primarily applied to other dishes until the croissant became a staple. By the 1860s, the croissant had secured its place as a breakfast favorite, with literary references confirming its status. Notably, in 1872, Charles Dickens mentioned the croissant in his periodical, likening it to other breads of the time. The transformation of the croissant occurred in the early 20th century, when French bakers adapted the recipe to replace the brioche dough of the kipferl with a yeast-leavened laminated dough. This change led to the creation of the croissant we recognize today. A significant contribution came from Sylvain Claudius Goy, whose 1915 book included one of the earliest recipes for the modern croissant, emphasizing its characteristic flaky texture. In the late 1970s, the introduction of factory-made, frozen croissant dough revolutionized production, making it accessible to many bakeries. By 2008, it was estimated that 30–40% of croissants sold in French bakeries were baked from frozen dough, marking a significant shift toward convenience while still honoring the pastry's rich history. Thus, the croissant’s evolution from a simple Austrian pastry to a beloved global delicacy reflects a beautiful convergence of culinary traditions and innovations, captivating those who savor its flaky, buttery goodness.
