Welcome to the Cake Decorators Q&A

Hi
How thick should the Ganache be under fondant, also hoe thick should the fondant be?
Thanks

Hi marylou

You’ll need to judge that by eye. It needs to be thick enough to encapsulate the cake in a firm smooth coating.
If you haven’t watched Paul’s free videos on ganaching, it will be worth doing so, you’ll find the videos here:

The thickness fondant is rolled out will be determined by the brand which you use. Most manufacturers will have guides. All you need to do is google the brand and ask for quantities and rolling out guides.
Paul uses the Renshaw’s brand in the tutorials, he talks about the thickness it should be rolled out here:

Hope this helps.
