AI am getting conflicting information. I am making a whipped milk chocolate ganache filling for cake - some things I'm reading say it should be refrigerated because it has air incorporated it does not last as long and then I am reading that putting the cake in the fridge once filled will make it hard....help? The cake will be filled tomorrow covered in buttercream and fondant an eaten on Sunday evening. Thanks for any help.
You will be fine , not to put in fridge. I would keep it in the coolest part of my house.That is what i always do, for that short period of time.
