When we were in Chicago for Fat Tuesday, it was not uncommon to have a friend or co-worker bring over a box of fresh Paczki. Paczki, a type of jelly- filled doughnut, originated in Poland (the official plural in Polish is pączki -pączek is the singular form), as a way to use up sugar and butter before the start of Lent. Unsurprisingly, Paczki Day is really big in Chicago, which has one of the biggest Polish populations outside of Poland. In Michigan, Hamtramck and Detroit are also epicenters of paczki culture. So what is a pączek like? The texture of a pączek is a bit denser than a jelly doughnut, and the jam fillings range from standard raspberry to more creative varieties, such as rose-hip or even guava (you may also see cream fillings). Louisa Chu on the WBEZ blog lists some top picks for Paczki in Chicago, and DNA Info rounds out the list even further. Rest assured, if you are in Chicago, you can get your Paczki fix.
