In a large mixer bowl combine 2 1/2 cups of the flour and the yeast. In a saucepan heat together the milk, sugar, shortening, and salt just until warm (115º - 120ºF.), stirring constantly to melt shortening. Add to dry mixture in mixer bowl. Beat at low speed with electric mixer for 1/2 minute, scraping sides of bowl constantly. Beat the mixture for 3 minutes at high speed.

By hand, stir in enough of the remaining flour to make a moderately stiff dough. Turn out onto a lightly floured surface and knead until smooth and elastic (8 - 10 minutes). Shape in a ball. Place the dough in a lightly greased bowl; turn once to greased surface. Cover' let rise in warm place until it doubles in size (about 1 1/4 hours). Punch down the dough; turn out on a lightly floured surface. Divide the dough in 2 portions.

Shape each in a smooth ball; cover and let rest for 10 minutes. Shape in loaves; place in two greased 8 1/2x 4 1/2 x 2 1/2 inch loaf pans. Cover and let rise till double (45 -60 minutes). Bake at 375ºF until done, about 45 minutes. If tops brown too fast, cover loosely with foil the last 15 minutes. remove from pans; cool. Makes 2 loaves
