The tradition of baking St. Martin's croissants dates back to 1891
This year on Saint Martin's Day the parish priest of the St. Martin's parish addressed the congregation with a request to help the poor. Bakeries produced croissants in the shape of a horseshoe (referring to the one lost by the white horse ridden by St. Martin), which were then distributed among the poor. This event is associated with the charity action, "Help your neighbours survive winter" conducted since 1994 by the Zamek Cultural Centre in collaboration with the Barka Foundation. However, the baking of croissants remains the best known tradition. Over the years the recipe has been continuously improved; currently a genuine St. Martin's croissant should be made from puff pastry and filled in 35% with a white poppy seed filling. The weight is also strictly defined - between 150 and 250 g. The quality of the Poznań croissants is controlled by a special Chapter appointed in 2003, which awards certificates and confirmations of quality certificates issued in the previous year. Bakeries holding such certificates guarantee that the croissants refer to the "best achievements of the Poznań bakers" and deserve the title of "Poznań St. Martin Croissant". According to bakers, every year Poznanians consume about 700,000 croissants (120 tonnes) on this day. This year they plan to bake as much as 400 tonnes of croissants! The reputation of the Poznań croissants goes beyond the city. Since 2000, the Poznań City Office has been sending these delicacies to the President and Prime Minister of the Republic of Poland, ambassadors and mayors of all provincial cities treating them as a showcase of Poznań and an important element of the city's promotion.
