Blend cashews and milk in a blender to a fine paste.
Mix paste and sugar and cook over low heat stirring till the sugar dissolves, then bring to a boil.
Continue stirring over medium heat, till the mixture leaves the sides of the pan, and becomes a dough like paste.
Remove from heat and when cool enough to handle, roll it on to a greased surface, with a greased rolling pin (roll before it cools).
Roll to 1/4cm / 1/8" thickness.
Now cover with the silver leaf and leave to cool, then cut into diamond shaped pieces.
