Heat oven to 425°. Melt shortening in small pan and set aside. Mix in paper bag flour, salt, paprika and pepper. Wash and pat dry chicken legs. Put 3 or 4 chicken pieces at a time in paper bag. Shake to coat chicken with flour mixture. Arrange chicken in a single layer in ungreased baking pan (13 x 9 x 2-inch). Drizzle the melted shortening on chicken. Bake, uncovered, 45 minutes or until chicken is tender.
