3/4 tspn baking soda

1. Grease a 2 qt. round casserole. Mix first 5 ingredients. With pastry blender or 2 knives used scissor fashion, cut in butter until mixture resembles course crumbs. Stir in raisins and caraway seeds.
2. In small bowl with fork, beat eggs slightly, remove 1 tblspn. and reserve. Stir buttermilk into remaining egg; stir into flour mixture just until flour is moistened. (Dough will be sticky).
