Last evening Ellena and I went out for dinner - to a hangi - what is a hangi you are thinking ??
It is a meal cooked under the ground in a pit with stones that are heated to a high temperature by fire, then the fire is put out, the food in wire baskets is put on top of the stones and the whole lot covered in cloth and then the soil from the pit - left to cook in the steam all afternoon.
The last layer of cloth is sacking which is very good at keeping the heat in - the smell by this stage is something else.
The veges are wrapped in tin foil
