Paczki Day (aka Fat Tuesday) may sound like an excuse to grab a dozen doughnuts, but it is so much more. The paczki is a Polish doughnut. In other words, it is fried dough filled with fruit preserves or sweet cream and topped with powdered sugar or glaze. Polish enclave Hamtramck is the ideal place for indulging in the beloved paczki. Historically, Fat Tuesday was an opportunity for Polish Catholics to eat all the sugar, eggs and lard in their house before Lent. Whether Catholic or not, however, Detroiters knew a good holiday when they tasted it and headed to Hamtramck — the city that has in the past made Fat Tuesday a week-long holiday. There is a good reason Detroiters head to Hamtramck: the city’s many Polish bakeries don’t stop at one or two varieties of the paczki. In addition to eating paczki, Detroiters can head to Hamtramck to simply celebrate them: Paczki Run 2017 (Feb. 25) is a 5K run through Hamtramck aimed at helping people make room for those paczkis.
