Question about cooking fudge

[Chocolot]

In my experience, fudge that is allowed to set on its own, will be shiny. If you knead it and work it, it will be dull.

I've never made the candy-maker version of fudge. It's always been the recipes that use marshmallows or marshmallow cream. I always stir in the chocolate and the nuts at the last minute and just pour that into the pan to set up. Other than that stirring, I don't overwork the fudge and still get dull fudge.

Following what Ruth said - if you cooked all your ingredients to the right temperature, cooled down, then added some fondant - you could pour out without working and it would set shiny.
