I have agreed to make a white cake with raspberry filling covered in fondant. I have refrigerated one fondant cake before and it got all sweaty and slimy so I haven't done it again. I think with using fresh fruit it needs to be refridgerated? The party is one Sat but I will be delivering on Friday evening as I have to be out of town. Does anyone have any tips? Also there will be black checkers on the side so if it sweats the black will likely run onto the white! Ack, I might have to change up the "fresh raspberries" and do a raspberry flavour filling instead.
I have made cakes with fresh Raspberries (cut in half), and some that I have pureed the fresh raspberries.
I have gone a total of 12 - 15 hours and kept cool (not refrigerated) and it has been okay.
DO NOT WASH YOUR RASPBERRIES! Washing them starts the bacteria process and they begin to go bad sooner.
You should, however take a damp paper towel to them (sort of like when you wash mushrooms).
If you do wash them...make sure you dry them with tons of paper towels.
This has worked successfully for me...but I do think you should let them know about keeping the cake cool.
