what is recipe on back of jar for fudge?

Answer Hello, here is the recipe: How to Make The Original Fantasy Fudge Recipe Ingredients 3 cups sugar 3/4 cup butter or margarine 2/3 cup evaporated milk 2 cups semi chocolate chips (I use Tollhouse for the original recipe) 1 jar of marshmallow crème, Kraft jet puffed 7 oz. jar 1 tsp. vanilla Chopped nuts are optional Directions Grease a 9 X 13 ” pan. Alternative and much easier is to line a 9 X 13″ pan with parchment paper, this allows a much quicker release and clean up. In a medium pot, mix sugar, butter and milk. Bring the mixture to a full boil using medium heat, stirring constantly so the sugar dissolves and the mixture does not burn on the bottom of the pot. ** Boil for five minutes. This is important! Five minutes exactly !! Remove the thickened mixture from the heat and add chocolate chips. Add the marshmallow crème and vanilla. Add nuts if desired. Pour into the prepared pan to cool.
