Here is something to try:
Will work with a turkey, large chicken or rabbit.
It comes out as if it was cooked by a Chinese chef in a hangi (Maori oven for those from SA)
You make a big pile of playdough about 2kg of salt and the same of flour, add water till it is moist enough to roll out like pastry about 5-6mm thick
Take 1/4 cup light soy sauce and add a tablespoon of honey. Melt in microwave and add a teaspoon of crushed garlic and crushed ginger.
Marinade the outside of the beast them put the remainder inside and sow up all the holes at both ends.
Wrap in aluminium foil and fold over the edges to seal.
Wrap the whole thing in the playdough and moisten and seal the joints.
Cook at 130 deg C for 4 hours (until it looks like a gold brown loaf of bread).
You will need an axe to cut the top off to get acces to the beast but it is well worth it and will keep a turkey very moist.
I have done it with turkey, chicken and a wild rabbit stuffed with rabbit back steaks. You could also stuff a chicken or turkey with quail.
If you realy want a traditional NZ hangi start digging a hole in the back yard. That is what we had at a friends place last year. Hard to beat.
