Chocolate Passionfruit Macarons

These are my must have flavour when visiting Pierre Herme or Laduree overseas for macarons, so I was surprised to hear Kerry Vincent declare on the Great Australian Bake Off that the two flavours don't 'go' well together! You do need to be careful to use the right chocolate though - too dark and you'll overpower the passionfruit, and if its not dark enough it will be too sweet.
