Sourdough Viennese pastry rolls

Just some random Viennese pastry rolls made with sourdough starter instead of original yeast biga.

Viennese pastries are made from enriched bread dough, meaning that they not only contain flour, water, salt and yeast, but also sugar, butter, and sometimes eggs. They are different from regular pastries because the dough is fermented and leavened with yeast instead of baking powder or soda.
