I decided to put everything in a pan except the chocolate, and reserved twelve butterbeans and two pickled walnuts. Heated the rest up and whizzed it with the hand held whizzer then poured the resulting mess into a cake tin and baked it.
When it was cool, I poured the melted chocolate over the top and decorated it with the butter beans and bits of pickled walnut, whereupon I cast a few spells. It may be a while until we know if the spells worked...
A total success I'd say, and highly recommended.
