2-1/2 to 3 cups all-purpose flour (I ended up using more like 3 1/4 cups flour)
2 tablespoons sugar
1 package (1/4 ounce) active dry yeast
1 teaspoon salt
1 cup (8 ounces) sour cream
1/4 cup water
3 tablespoons butter, divided
In a large bowl, combine 1-1/2 cups flour, sugar, yeast and salt. In a small saucepan, heat the sour cream, water and 2 tablespoons butter to 120°-130°; add to dry ingredients. Beat on medium speed for 2 minutes. Add egg and 1/2 cup flour; beat 2 minutes longer. Stir in enough remaining flour to form a soft dough.
Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. (I let my Kitchen Aid do the work with a dough hook for 6 minutes) Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place until doubled, about 1 hour.
Punch dough down. Turn onto a lightly floured surface; divide into 12 pieces. Shape each into a ball. Place in a greased 13-in. x 9-in. baking pan. Cover and let rise until doubled, about 30 minutes.
Bake at 375° for 25-30 minutes or until golden brown.(With mine the tops were brown after 10 minutes. So I just draped foil on top of the rolls and cooked for 10 more minutes. Mine were ready after 20 minutes) Melt remaining butter; brush over rolls. Remove from pan to a wire rack. Yield: 1 dozen.
