St. Martin's croissant (Polish: rogal świętomarciński) is a croissant with white poppy-seed filling traditionally prepared in Poznań and some parts of Greater Poland region on the occasion of St. Martin's Day (11 November).
In Poznań, the tradition of baking St. Martin's croissants on 11 November certainly existed in 1860, when the oldest known advertisement for the pastry was published in Dziennik Poznański.
However, there is a popular legend that the tradition in its present form was born in November 1891. As St. Martin's Day was approaching, the parish priest of St. Martin's parish, Fr Jan Lewicki, appealed to the faithful to do something for the poor, following the example of the patron saint. The confectioner Józef Melzer, who was present at the mass and worked in a nearby confectionery, persuaded his boss to revive the old tradition. The wealthier Poznań residents bought the delicacy and the poor received it for free. The custom of baking in 1901 was taken over by the Association of Confectioners. After the First World War, Franciszek Rączyński returned to the tradition of giving gifts to the poor, and after the Second World War, Zygmunt Wasiński saved the croissant from oblivion.
Ingredients
