I have been asked to make my friends wedding cake and her wedding is going to be in a hot month in Australia! My question is, I don't want to use fondantas a finish as in our hot humid weather it can be a disaster! And i don't want to use white chocolate ganache as a finish as its more yellowy in colour and that will melt if it comes out of the fridge as well. My question is can royal icing be used as a finish to hold up under heat? Will it melt or will it stay hard and sturdy?
Thanks for your help/advice in advance! :)
