How to Make It
Trim fat from chops. Combine flour, salt, and pepper in a large zip-top plastic bag. Add chops; seal bag, and shake to coat chops with flour mixture. Remove chops from bag, reserving the remaining flour mixture. Place the flour mixture in a small bowl. Gradually add 1/2 cup milk, stirring with a wire whisk until blended.
Melt margarine in a large skillet over medium-high heat. Add chops; cook 3 minutes on each side or until browned. Add milk mixture; cover, reduce heat to low, and cook 30 minutes, stirring occasionally.
Turn the chops over. Add remaining 1 cup milk; cover and cook 30 minutes, stirring occasionally.
Uncover skillet, and cook the chops an additional 15 minutes or until the liquid is reduced to 1/4 cup (the sauce will be very thick). Spoon sauce over chops.
