In large mixing bowl combine 1½ cups flour, yeast, sugar, salt, Buttermilk Blend, baking soda and shortening. Mix well. Add very warm water to flour mixture. Blend on low speed until moistened. Beat 3 minutes on medium speed.
By hand, gradually stir in enough remaining flour to make a firm dough.
Knead on floured surface until smooth and elastic (about 5 minutes).
Place in greased bowl, turning to grease all sides.
Cover; let rise in warm place until doubled (about 20 minutes).
Punch down.
Divide dough into two balls.
Shape each ball into 12-inch rope and cut into 12 pieces.
Form pieces into balls.
Place about ½ inch apart on greased cookie sheet or 15 x 10 inch pan.
Cover; let rise in warm place until almost doubled (about 20 minutes).
Bake in preheated 400°F oven 15 to 20 minutes, until golden brown.
