Friz - you are planning far more detail than I am capable of at the moment!
EPPM - do you mean for a gift for someone, or are you planning like Friz . If gift, then try some of the truffles from here. (Choc bars not great, but the truffles that dh bought me for Christmas were good).
If looking just for everyday treat, Waitrose (and prob other places) sell Lyme Regis dark choc covered marzipan bars, which are v yummy.
