"This rich and tender sour cream and yeast cookie is delicious and so lovely with its many delicate layers and twists. It is a classic and historic recipe for which many variations can be found. This updated version uses all butter and a food processor for wonderful flavor and ease of mixing. The rich yeast dough actually contains no sugar, but the sweetness and the layering results from well sugaring the dough and work surface, while rolling and folding it several times prior to cutting and shaping the cookies."
