This is a great comical book with step by step instructions on how to cook a traditional hangi. (New Zealand Maori Roast).
You can cook a hangi just as easily for 4 people as you can for 20 people.
This would work well as a catering business in the States because it is unheard of and absolutely delicious.
So why don't you sit back with a beer and enjoy the entertaining instructions in this book.
