I know of two recipes which are very good for fudge and will find the recipes when I get home from work. I believe the main difference between the two is that one uses marshmallows and evaporated milk and takes longer to cook than one which uses condensed milk and marshmallow creme.

There are two other recipes I now of that are like fudge, but also use peanut butter or unmelted marshmallows and possibly candied fruit.

What brand and type of chocolate are you planning on using? There are 3-4 major brands of chocolate chips in the US.
