I would like to try white chocolate ganache under fondant for the first time. What is the best recipe and how much do I need to make to cover an 8" and 12" round?
i think that for white chocolate ganache the ratio is 3;1. Three parts chocolate to 1 part heavy cream. i have no idea how much to use for those sizes, but keep in mind that you only need to spreading very thinly and also the leftovers will keep in the fridge. Good luckl!
You can get by with 60 oz of white chocolate to cover 12" + 8", but I prefer 72. If you are also filling with ganache, you'll need more. It's much better to have a little left over than to not have enough to do the job properly.
I am well curious to a recipe for this. I have been wanting to try it, but am to chicken that it will turn into disaster. Maybe one day...
Like all things, each will do it differently. Vagostino posted that she spreads thinly. I like to have a good layer of ganache and a thinner layer of fondant over it. Some may like it reversed.
I used 72 oz. of white chocolate for the Harley cake in my photos, which was 12" + 8", and I did not fill with it. I guess the ganache layer was somewhere between 1/8" and 1/4".
I started with 48 oz. for the Princess Cake, same size, ran out and had to make more. I made another 12 oz. batch and barely scraped by.
I do use the ganache to straighten up the sides and level off the top if there is any uneveness, so maybe that's why I use a lot.
