Cookbooks aren't just a bunch of recipes. They often contain insights into the political and cultural contexts of their time. Never was there a better example of this than Australia's oldest continuous community cookbook, The Barossa Cookery Book. Initially released in 1917 as a war fundraiser it's now in its 33rd edition. Sheralee Menz and Marieka Ashmore, also known as Those Barossa Girls, have begun a companion venture with The Barossa Cookery Book Project.
