Fat Thursday is a traditional Christian feast marking the last Thursday before Lent and is associated with the celebration of Carnival. Because Lent is a time of fasting, the days leading up to Ash Wednesday provide the last opportunity for feasting (including simply eating forbidden items) until Easter. Traditionally it is a day dedicated to eating, when people meet in their homes or cafés with their friends and relatives and eat large quantities of sweets, cakes and other meals usually not eaten during Lent. Among the most popular all-national dishes served on that day are pączki in Poland or berliner, fist-sized donuts filled with rose hip jam, and angel wings (faworki), French dough fingers served with powdered sugar.
In Poland, Fat Thursday is called Tłusty Czwartek. People purchase their favorite pastries from their local bakeries. Traditional foods include pączki (doughnuts), which are large deep-fried pieces of especially rich dough, traditionally filled with plum or rose petal jam (though others are commonly used) and topped with powdered sugar, icing, or glaze. Angel wings (faworki) are also commonly consumed on this day.
Rouladen or Rinderrouladen is a German meat dish, usually consisting of bacon, onions, mustard and pickles wrapped in thinly sliced beef which is then cooked. The dish is considered traditional also in the Upper Silesia region of Poland where it is known as rolada śląska (Silesian roulade) and in the Czech Republic where it is known as španělský ptáček (spanish bird).
Beef or veal is typically used, though some food scholars tend to believe that the original version was probably venison or pork, and pork is still popular in some areas. The beef rouladen as we know them today have become popular over the last century. The cut is usually topside beef or silverside since this is the cheaper cut. The meat is cut into large, thin slices.
The filling is a mixture of smoked and cooked pork belly, chopped onions and chopped pickles (gherkins) which is at times varied by adding minced meat or sausage meat. The mixture varies from region to region. Rouladen are traditionally served for dinner. Red wine is often used for the gravy.
Serving
Rouladen are usually served with either potato dumplings or mashed potatoes and pickled red cabbage. Roasted winter vegetables are another common side dish. The gravy is an absolute requirement to round off the dish and is usually poured over the meat. Spätzle are a good complement to the dish since they soak up the gravy well.
Originally considered as a dish for common people, it is today enjoyed by many as a festive dish.
