Ruth Greenwald (left), co-owner of Yum Yum Donuts, 3741 Oakwood in Melvindale, positions paczki on a rack Tuesday while her husband, co-owner Jeff Greenwald, applies icing to a previous batch. Paczki are doughnuts, typically eaten by Polish American Catholics on the Tuesday before Ash Wednesday. Traditionally the reason for making paczki was to use up all the lard, sugar, eggs and fruit in a house before Lenten fasting began. The rich, round, deep-fried doughnuts are covered with powdered sugar or icing and filled with fruit or cream filling.
