More than 206 countries participated in the awards this year, with food writers from around the world attending the ceremony in Yantai.
The Eggers said they were proud to represent their country on the international stage.
"It is great to be able to showcase what New Zealand has to offer and the quality of the product that we are able to produce".
The couple are no strangers to success at the Gourmand awards: their last book, Volcanic Kitchens: Come And Join Us, won Best Photography Cookbook for New Zealand in 2013.
That book celebrated the cooking traditions of Rotorua and wider Volcanic Plateau; with their latest effort, the Eggers have cast their net wider - perhaps channelling the mindset of Monty Python's John Cleese.
"If God did not intend for us to eat animals, then why did he make them out of meat?"
