Making 4 tier wedding cake with buttercream frosting and fillings that need to stay in refrigerator. Made bow using fondant with tylose added and plan to attach to side of third tier using melted chocolate. Should I stack and attach bow today and keep in refrigerator until wedding tomorrow or should I not attach the bow until some time later, maybe even after I travel with it for about 30 minutes. Any advice would be appreciated as I have never refrigerated a wedding cake before. Also wondering if the Super Pearl Luster Dust will get dull in the fridge. Thanks.
The luster dust will be fine.
Are you attaching the bow to something other than buttercream? If you're putting it on a fondant band, for example, it won't go anywhere after you attach it with the chocolate. If you're just sticking it onto the buttercream it will probably be fine but I'd use more buttercream, not melted chocolate.
Yes, I will be attaching it to a fondant band but I still worry that it might collapse or droop (the bow). Should I keep it "stuffed"?
