If you do not have a breadmaker, mix 2 c. of the four, the sugar, butter, salt and yeast in a large bowl. Add water, milk and egg. Beat on low speed, scraping bowl frequently, 1 min. Then do the same on medium speed. Stir in enough of the remaining flour to make dough easy to handle. Turn onto lightly floured surface, knead until smooth and elastic (5 min). Place in a large greased bowl; turn greased side up. Let rise in a warm place until double (about 1 hr.) Punch down dough. Cover with a dry cloth and let it rest on a floured surface for 10 min.
