I have a wedding to do this Saturday. Bride wants 200 cupcakes 1- 7" round to freeze and a mini of the 7" to cut at the reception. 100 bridal cupcakes and 100 grooms cakes. The bridal cakes need 1 sweetpea each. I have to travel 1 hour or so to deliver them and it's hot here especially with the heat index. Should i use buttercream and hope it doesn't melt on the way or use royal!? Help me! I think I know what I should do but would like some others advise as well. Thanks for any help you can give

humidity is bad for royal icing (since it contains no fat to repel moisture, it will absorb moisture and get soft and runny -- much like you want it to when you're making color flow decorations). heat is bad for fats, since they melt (but hydrogenated fats like shortening hold up better). i would go with buttercream, freeze the cakes, and travel with them in the air-conditioned passenger section of your vehicle (not in the trunk).

Thanks Aunt-Judy that is what I thought. But you can't ever be too sure about these things. This is why I love this site b/c you can check and recheck your thoughts and ideas! Thanks alot!
