When you are using ganache under white fondant do you use white chocolate ganach? If so what reciepe do you use?
I use dark chocolate ganache under whatever coloured fondant I am using, white gannache just doesn't have the same qualities and is much more temperamental to work with.
I used dark chocolate ganache under my fondant once. I use royal icing now or a crusting. I used a 2:1 ratio. Eg. 1 lb semi sweet chocolate chips and 1/2lb heavy cream. I had to use two layers of fondant on my cake. It was my 1st time using ganache under a cake and it didn't set properly. Was still sticky and if i poked it, the ganache would leave an indent. I put it in the fridge overnight but when it came out it condensed. The cake looked really nice though...but with 2 layers of fondant. The 1st fondant application didn't look smooth and was showing the chocolate cuz I rolled it thin.
