Bests & Worsts Reviews from Amazon

This is my first ever review of a recipe from a book on Amazon. This recipe is bad! After stirring it up and doing all the prep, I googled blue zone sour dough bread recipes. Apparently most recipes call for two cups of water not just 1 as in the recipe in the book. In addition the cooking temperature and time are not good because it was still raw in the middle after cooking it an additional 15 minutes. Epic fail. I wasted starter, ingredients and several hours. I think the Blue Zone author should use a recipe tester.
