Chive Pinwheel Rolls

Directions

1. In a large bowl, combine 2-1/2 cups flour, sugar, yeast and salt. In a small saucepan, heat milk, oil, water and mashed potatoes to 120°-130°. Add to dry ingredients; beat just until moistened. Add egg; beat until smooth. Stir in enough remaining flour to form a soft dough.
2. Turn onto a floured surface; knead until smooth and elastic, 6-8 minutes. Place in a greased bowl; turn once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
3. Turn dough onto a floured surface. Roll into a 15x10-in. rectangle. In a bowl, combine sour cream, chives and egg yolk. Spread over dough to within 1/2 in. of edges.
4. Roll up jelly-roll style, starting with a long side; pinch seam to seal. Cut into 1-in. slices. Place cut side down in a 13x9-in. baking pan. Cover and let rise until doubled, about 1 hour.
5. Bake at 350° for 30-35 minutes or until golden brown. Brush with butter. Cool on a wire rack. Refrigerate leftovers.
