I've been looking on-line for Christmas gift inspiration and I can't remember where it was, but one of the offerings was a chocolate "pizza" studded with red cherries, green pistachios, nuts etc! It ocurred to me that this could be made easily at home using a large slab of chocolate melted in a round baking tin (like a victoria sandwich tin) and studding with whatever your recipient likes , e.g brazils, Smarties, marshmallows etc. It looked quite thin so in fact a large slab would probably make at least 2 "pizzas". When finished it just needs to be wrapped in sellophane and trimmed with a ribbon and label.
There also lots of regular "studded" bars on the high street and they are extremely expensive - £10 -12 is average. It has got to be cheaper to "do it yourself"!
