Share 'Fondant & Margarine in a ganache recipe??!!'

Hi, I have recently seen a range of truffles using fondant and margarine in their ingredients list. I have seen glucose and invert sugar used in making a ganache before, but fondant - I had never heard of using this. I would imagine the margarine is used to keep the cost down, rather than using butter. Anyone have any thoughts on using these types of ingredients in a ganache? I was pretty shocked…
