Servings: about 3 pounds DIRECTIONS: Peanut Butter Fudge: Grease 10 by 18 cm baking pan; set aside. (If making only one kind of fudge, use 8 by 20 cm baking pan.) Into 6 litre heavy saucepan, measure sugar, milk and salt. Over medium heat,heat to boiling, stirring constantly. With candy thermometer in place, cook, without stirring, until temperature reaches 235-F or soft ball stage (when a small amount of mixture dropped into very cold water forms a ball which flattens on removal from water). Remove saucepan from heat. Without stirring, allow mixture to cool to 110-F or lukewarm, about 45 minutes (bottom of pan will feel comfortably warm). Stir in marshmallow creme and peanut butter. With wooden spoon, beat mixture until it holds its shape and loses some of its gloss, about 5 to 7 minutes. Turn fudge into prepared pan. Allow fudge to set, about 30 minutes.
