I am making a cake for my dh's 50th class reunion. I have a class picture that i've had done into an edible picture. I've never done one so I'm worried about a couple of things.

1. I'll be using bc. Can I put the image on when I decorate the cake the day before the event or should I wait until the morning of? (I've seen where the fat in the bc may cause problems)

2. The cake will be purple with gold trim. Can I use the image on purple bc or should I use white?

Thanks for any help you can give.

From my experience you want to put the image on a day or so ahead to allow it to meld to the icing underneath.White BC is better since most of the images are made with a non translucent background and the colored icing underneath will looked smeared and not blend in..Or at least that is what happened when I tried to do this with black icing.

Thanks Kiddiekakes!

yes, it will definitely work best on a white background! when it melds with the bc it will take on the color (or lack thereof) of the icing.

if you make it a day ahead (different products will behave differently, in terms of melding time), it might help to keep it away from light to avoid any discoloration or fading; try to deliver it in a box with no window ...
