I am looking for some sort of portion control when cutting cake. Some people have given me differnt ideas on the portions depending on the size or make of the cake. Does any one know the portions best cut for a 28cm round white chocolate cake? it is to be used as a wedding cake and I have been told that wedding cake portions are read differently? Is this right? Thankyou in advanced. I have searched the net, read books and cant seem to find a common answer. Again thankyou!
