Welcome to the Cake Decorators Q&A

If I apply a ganache crumb covering to a madeira cake and 24 hours later apply the fondant icing will this be ok for a wedding in 7 days time.

Good Morning gillian.hedger

As along as the ganache has set firm to touch, it will be fine to cover the cake with fondant icing.

If you are at all all unsure , Paul’s free tutorials on how to use ganache and using sugarpaste , will both be an excellent guides. Here are the link:

Using Ganache

Basic Sugarpaste Skills

If the ganache is too dry for the sugarpaste to stick, fine mist the surface of the cake with a little cool boiled water or just moisten it using a wide soft brush with, either vodka or boiled cooled water. The ganache should just be tacky and not saturated.

could i use two fillings for madeira cake…eg. one layer lemon curd and one layer raspberry jam?

That would be fine as the flavours are most complimentary. However, just be aware that both fillings are very slippery which could cause the layers to slide. This can be prevented by taking a few precautions, information which you can find in several links here:

I usually only put filling i.e. jam in the middle and pipe the buttercream over it..then push down to level the cake ..pop in fridge for a little while to firm buttercream up and then ganache it. would lemon curd and raspberry go together??

I put more cream into my white choc ganache as it was a bit oily. however now i find it may be a bit too soft. It holds its shape ok but i am worried it may not form that crust. Can i add some more melted white choc to the mix?? Doing the cake now.
