In a large bowl, thoroughly mix 2 cups flour, dry milk solids, sugar, salt and undissolved Fleischmann's Active Dry Yeast. Add Fleischmann's Margarine. Gradually add tap water to dry ingredients and beat 2 minutes at medium speed of electric mixer, scraping bowl occasionally. Add 3/4 cup flour. Beat at high speed 2 minutes, scraping bowl occasionally. Stir in enough additional flour to make a stiff dough. Turn out onto lightly floured board; knead until smooth and elastic, about 8 to 10 minutes. Place in a greased bowl, turning to grease top. Cover; let rise in warm place, free from draft, until doubled in bulk, about 45 minutes. Punch dough down; let rise again until less than doubled about 20 minutes.

Divide dough in half; cut each half into 10 equal pieces. Form each piece into a smooth round ball. Place on greased baking sheets about 2 inches apart; press to flatten. Cover; let rise in warm place, free from draft, until doubled in bulk about 1 hour.

Bake at 375 degrees F. for 15 20 minutes, or until done. Remove from baking sheets and cool on wire racks.
