Wikipedia: Danish pastry
Danish pastry or just Danish (especially in American English) is a multilayered, laminated sweet pastry in the viennoiserie tradition. The concept was brought to Denmark by Austrian bakers and has since developed into a Danish specialty. Like other viennoiserie pastries, such as croissants, Danish pastry is a variant of puff pastry made of laminated yeast-leavened doughs, creating a layered texture.
