Soften yeast in warm water. Combine hot milk, sugar, salt, and oil. Cool to lukewarm. Stir in 1/4 of the flour; beat well. Add the softened yeast; mix. Add enough of the remaining flour to make a stiff dough. Knead till smooth. Shape dough in ball; place in a lightly greased bowl. Cover and let rise until doubled. Punch down. Let rise again until doubled. Cut in portions. Shape each in a smooth ball. Cover; let rest 10 minutes. Shape in round loaves. Place on greased pans. With a sharp knife, slash an "x" or a cross on top, and let rise until doubled. Bake at 400° F for 35 minutes or until done. Brush tops with butter
