Place 1/2 cup warm water in large, warm bowl. Sprinkle in yeast; stir until dissolved.
Add remaining warm water, warm milk, sugar, 1/4 cup butter, salt and 2 cups flour; blend well. Stir in egg and enough remaining flour to make soft dough.
Knead on lightly floured surface until smooth and elastic, about 4 to 6 minutes. Place in greased bowl, turning to grease top. Cover; let rise in warm, draft-free place until doubled in size, about 1 hour.
Punch dough down. Remove dough to lightly floured surface; divide in half. Roll each half to 12-inch square, about 1/4-inch thick.
With sharp knife, cut each square into six (12- x 2-inch) strips. Cut each strip into three (4- x 2-inch) rectangles. Melt remaining butter; brush on rectangles.
With dull edge of knife, crease each rectangle slightly off center; fold at crease. Arrange in rows, slightly overlapping, on large greased baking sheet, with shorter side of each roll facing down.
Allow 1/4-inch of space between each row. Cover; let rise in warm, draft-free place until almost doubled in size, about 30 to 45 minutes.
Bake at 400 degrees F for 15 minutes or until done. Remove from pan; cool on wire rack.
