Yield: 1-1/2 dozen
In a mixing bowl, dissolve yeast in water.
Beat in buttermilk, oil, sugar, salt, baking soda and 2 cups of flour until smooth. Stir in enough remaining flour to form a soft dough.
Turn onto a floured surface; knead until smooth and elastic, about 6 to 8 minutes.
Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled in bulk; about 1-1/2 hours.
Punch dough down. Divide into 18 pieces; roll into balls. Place on greased baking sheets or parchment paper placed on a baking sheet. Cover and let rise until doubled; about 30 minutes.
Bake at 400 degrees for 15 to 20 minutes or until golden brown. Cool on wire racks.
*No buttermilk? Substitute 1-1/2 tablespoons lemon juice and enough milk to make 1-1/2 cups.
