First the sugar, evaporated milk and butter/margarine are mixed.
Over medium heat, stirring constantly the mixture is brought to a rolling boil for four minutes, still stirring constantly.
After four minutes remove the pan from the heat and add the marshmallow creme and chocolate chips.
Next add the nuts (if you want them) and vanilla.
The fudge is them poured into a pan. The recipe says to use a 9 inch square pan but I have always used a 9x13. I also grease the pan rather than lining it with foil. For this step I had to have Mike come and assist since I have apparently lost the ability to hold up a pan and get the contents out, not that he minded since one of his roles is official taster and he got to walk away with the spoon afterwards (his other role is dishwasher, thank goodness). Here is the fudge in the pan cooling.
Later this evening or tomorrow I will make a pan of plain fudge.
