(You will need 12 sheets of greaseproof paper (cut in squares)).
Place all the ingredients in a deep dish and refrigerate, covered, for about half an hour.
Pre-heat the oven to 200°C.
Separate the greaseproof paper into pairs and place the ingredients on six double sheets, making sure a little of each ingredient is included each time. Wrap the paper into packages and tie firmly with kitchen twine.
