In the UK, Fat Tuesday is known as Shrove Tuesday -- a day celebrated by eating a stack of fluffy pancakes. In Poland, it's Paczki Day -- which refers to the jelly-filled doughnuts they eat the day before lent. And for Americans, Mardi Gras is basically synonymous with New Orleans, home to some of the best (and richest) foods in the country. We take our Fat Tuesday food very seriously, and that means finding the most delicious recipes to celebrate.
