Even though they are often referred as Toruń gingerbread cookies, pierniki derive their name from the Polish word pieprz, meaning pepper. The authentic recipe is still a closely guarded secret, but they are traditionally made with wheat or rye flour, honey, and a blend of spices, such as cinnamon, nutmeg, pepper, and cloves.
In the past, pierniki were mostly shaped with the help of intricate wooden molds, but nowadays the dough is often cut into heart or club shapes. Modern day pierniki come in various versions that are often glazed with chocolate or sugar and filled with fruit jams, chocolate or marzipan.
