How to Make It
Preheat oven to 425°.
Lightly spoon flour into dry measuring cups; level with a knife. Sift together flour, baking soda, and salt into a large bowl; stir in raisins and sugar. Combine buttermilk and egg; add to flour mixture, stirring until dough forms. Turn dough out onto a lightly floured surface; knead lightly 4 times with floured hands (dough will be sticky). Divide dough into 12 equal portions, shaping each into a ball (cover remaining dough to prevent drying). Arrange rolls on a lightly floured baking sheet. Bake at 425° for 10 minutes. Reduce oven temperature to 400° (do not remove rolls from oven); bake an additional 8 minutes or until rolls sound hollow when tapped.
