Above is the deconstructed salade niçoise from what the NPR food blog the salt says "could rank among the geekiest of all cookbooks". The hexagonal dishes (made for scientific laboratories as containers for substances to be weighed on scales) not only reflect the gameboard with blocks of different colours and textures but also allow a variety of dietary restrictions to be catered for by keeping the foods separate.
The author, Chris-Rachael Oseland has produced previous books - a guide to Steampunk cocktails called SteamDrunks: 101 Steampunk Cocktails and Mixed Drinks
and a Dr Who Cookbook called Dining With The Doctor: The Unauthorized Whovian Cookbook.
Her food blog is at Kitchen Overlord and looks great fun.
I have only played Settlers of Catan once, when visiting Germany, but I could be tempted again if someone cooks a vegan spread. Though for the salade niçoise there is a strange braised dried tofu in sauce thing from Marigold that people always assume is tuna when I am eating it in public. Much better and tastier than the seitan that the author recommends as a substitute. It is a tofu you don't have to mess with for hours before you can eat and enjoy it.
