place chocolate chips or buttons (or chopped chocolate if using a block), cocoa butter drops (chopped if using chunks), sunflower lecithin and icing ‘sugar’ in a bain marie over gently simmering water, and stir until completely melted.
remove bowl and incorporate nutella and crumbed hazelnuts.
fill 15 chocolate mould holes half way, place a whole hazelnut in each and top with remaining mixture.
freeze until set, unfold and serve.
Notes
THIS is the chocolate mould I used (U.S. option HERE).
No need to keep chilled.
