Originally a creation of Roman-Catholic monks, and now popular internationally, kringle is a delicious flaky pastry, usually shaped as a pretzel and filled with various ingredients. It was primarily introduced in Denmark, under the influence of Austrian bakers, and later it spread throughout Nordic countries and eventually to the United States, where it gained great success.
Each region has created its distinct varieties, using local and seasonally available ingredients. In Denmark, kringle is usually made with either puff pastry or yeasted dough, filled with sweet concoctions that include butter and sugar, marzipan, and raisins.
In the 19th century, Danish bakers introduced the tradition of preparing kringle to the United States, specifically Racine Wisconsin, where the pastry was slightly adapted to the now-famous oval shape. Kringle in Racine is always made with traditional Danish laminated dough, in which the pastry layers are generously spread with butter and filled with the lavish combination of fruits, nuts, or cream cheese.
