Hi Ellie – oh I really empathize with how you felt – delivery is always terrifying for me. Last year on one of the hottest days -I had safely delivered a two tier cake to a friends house but the next day – just as hot – my friend then drove the cake to another venue and the cake apparently started to collapse – eeeeek!!!!! Oh my goodness I can’t tell you how sick I felt when I was told. I had used really good quality dowels and more than enough to support the top tier but now I also only use ganache on the outside of my cakes. If the cake is more than two tiers I assemble on site and always try to take someone to help me. Xx
