Old Fashioned Fudge

0 In a large heavy stockpot, combine the sugar, butter and evaporated milk.
2 Cook the mixture over moderate heat, stirring constantly, until it comes to a full boil.
15 Set a timer for exactly 5 minutes.
4 Boil the mixture, stirring constantly and making sure that it doesn't scorch, for 5 minutes exactly.
6 Remove the pot from the heat and quickly stir in the chocolate, marshmallow cream, vanilla, pecans, and salt.
8 Stir the fudge mixture until it is combined thoroughly. Pour the mixture into a greased 13 x 9  inch pan that's been lined with parchment paper and sprayed with no stick spray.
10 Chill the fudge for 2 hours, or until it is firm.
16 Pull the parchment out of the pan and lay it on the counter.
12 Cut the fudge into squares.
14 Store in an airtight container lined with wax paper, separating the layers with wax paper, in a cool place - but not the refrigerator.
