Add vanilla essence to caster sugar to give vanilla sugar. Melt the chocolate block in a bowl over a pan of boiling water. The bottom of the bowl must not touch the water or the chocolate will congeal. Mix the baking powder, some salt and flour together in a bowl. Blend the sugar and butter in a blender. Put 3 egg yolks in a bowl and whisk well with a fork then add to the melted chocolate. Mix in the sugar and butter mixture then beat everything together with a whisk. Add in the flour mix while whisking then the sultanas and a little of the liquid from marinating. Add the nuts and the white chocolate pieces. Spoon the mixture into a buttered baking tray then smooth to a flat surface. Place in a warm oven to cook for 20 minutes. The end result should look crisp and be soft in the middle.
