This recipe was given to my Mom in the 1960's by a lady in our small town in southern Arizona. I found the recipe written in my Mother's handwriting on the back of an old sweepstakes letter. It was tucked between the pages of Mom's "Joy of Cooking" cookbook(Copyright 1931). She titled it simply "Emily's Fudge"
Heat sugar and canned milk in heavy sauce pan. Stir until sugar is dissolved and mixture comes to a boil. Boil 12 minutes after sugar dissolves.
Place bittersweet chocolate, chocolate chips, chocolate bars and butter in large heat resistant bowl. Pour hot milk/sugar syrup over the chocolate and butter. Stir well to dissolve the ingredients. Add chopped nuts and vanilla. Stir just until blended.
Pour into large buttered pan (or pan lined with buttered foil) and let cool until set, then cut into squares.
(Makes approx 5 pounds fudge)
