I am new to all this cake making business and very excited to be making my niece a birthday cake. I am making a fondant covered mud cake with chocolate ganache underneath. I am wanting the cake complete for next Friday. I have made the cake and have it in the freezer, but want to ask how many days before Friday could i ganache the cake. Could i do it this weekend and keep it in the fridge, before covering it?
Any advice would be appreciated
You should be find to make your ganache and cover your cake this weekend.
The big thing to remember when making ganache is to ensure your cream boils (or use UHT cream) in doing so you have pasteurized the cream and it will keep in ganache form for a very long time indeed.
One week is neither here nor there to well made ganache, mud cakes with ganache will keep (and improve!) for ages.
Just make sure the cake is well covered in the fridge so it doesn't pick up flavours from other foods in the fridge.
