In which city did the croissant become popular in France after being introduced? Paris. The pastry gained attention in France through Paris, where an Austrian-style bakery introduced Viennese specialties that influenced French bakers.
In 1838 or 1839, Austrian artillery officer August Zang founded the Boulangerie Viennoise at 92 rue de Richelieu in Paris. The bakery sold items including the kipferl and Vienna loaf. Its popularity helped inspire French imitators and encouraged the development of the French viennoiserie tradition.
The croissant did not appear in Paris fully formed as the modern flaky pastry. French bakers gradually adapted the Austrian crescent-shaped roll, changing the dough and introducing the laminated, butter-rich structure now associated with croissants. The earliest known recipe corresponding closely to the modern croissant was published in Paris in 1906.
A common misconception credits Marie Antoinette with introducing the croissant to France. That story is widely repeated but lacks solid historical support. Paris is the defensible quiz answer because it was the city where the Austrian model was introduced, popularized, and transformed within French baking culture.
