Truffles aren't hard to make at all, and if I got a truffle that was fondant in the middle I might just have a few words for the one who made it..
Fondant is so not a truffle.. now if I knew about this before and ordered anyway then no harm no foul, but if i was expecting a truffle and got chocolate covered fondant.. uh uh.. no way. Truffles are creamy and silky.. not chewy like fondant would be.
You don't have to whip the ganache at all.. infact most recipes I have ever seen for truffles are just chocolate and heavy cream with maybe a splash of amaretto, frangelico, cointreau, or some other liquor added to it for flavor. Chill that in the frige and scoop and roll.
I do a 1.5:1 ratio of chocolate to cream and flavoring if wanted.. make the ganache by pouring hot heavy cream over the chopped chocolate and let it stand for 5 minutes and then whisk until smooth and add in your desired flavoring.. pour into a container and chill in the fridge. When set simply scoop the chocolate ganache with a small scoop, roll in your hand quickly to shape and then roll in your toppings.. I like cocoa powder but you can do chopped hazelnuts or dip them in chocolate or whatever you think would be good.
Mmmm.. now I want to make truffles.. maybe my family will be lucky and get some for x-mas.
