I am making one today to eat! About to roll it out and bake, just a question for the icing, I don't want to use Royal Icing because DS has an egg allergy(welllll he has pretty much grown out of it but want to be safe and not use raw egg anyhooooo) and I have some white choc melts to use instead - just wondering if I will need to mix the choc with some icing sugar as well or cream to make it like a ganache??? Anyone got any ideas!!
