Simply you will need some white chocolate, butter, biscuit and some dried fruits.
Glace cherries are fine, but so are any glace fruits - colour wise its good to have some green Glace cherries are fine, but so are any glace fruits - colour wise its good to have some green - either cherries or angelica works well.
As its Christmas I have used dried cranberries!
For about 200gms of White Chocolate you will need just over half the amount of butter - about 120gms of butter.
I Microwave these together on a medium heat - stirring every 1/2 minutes - you want to melt and combine not cook! Alternatively, you can use a bowl over a saucepan of simmering water - taking care the bowl is not touching the water. When melted set aside to cool to nearer room temperature.
In a small bowl break up and pound to crumbs (not dust) 6 sweet biscuits, something like Rich Tea or Nice Biscuits. Add to this 2 tablespoons of raisins, 3 tablespoons of dried cranberries and some diced angelica or green cherries. Stir these well through the choclate butter mixture and then chill in the fridge for 1 - 2 hours. Before it is firmly set take out and make two rolls of the chocolate using cling wrap, double wrapping and rolling into an even sausage shape.
Return to refrigerator and leave until ready to serve when they can be cut into slices and served.
