After hearing a radio interview with the author I decided to try this cookbook. The idea is interesting and worked well for my family. I don't like cooking, and I REALLY don't like cleaning the kitchen, so it was nice to do the bulk of both of those things in one day and then be done with it. I did still need to make a little extra most nights though (vegi's/ side dish). Since we get our produce through a CSA and it's unpredictable what we'll get, this system was perfect for incorporating last minute sides. The recipes themselves were "interesting" and very different from the way I'm used to cooking. A lot of them call for pre-made packets or mixes, or canned fruit and vegetables. I've always just used fresh produce, or put together my own "taco seasoning", so this was new. It felt like something out of the 50's (and probably not very healthy!). I think I opened more cans in one day than I had all year! There is A LOT of meat in this plan which was new for me too. Often times I'll use something like tofu instead, but not with this book! Also, there are burgers in every single meal rotation I've made so far. So we're all pretty sick of them now. Some of it I won't make again, like the brined fish (pointless), ham bake (turned out to be ham soup in a soggy pie crust) and the french bread pizza (took up a lot of freezer space and just wasn't good). Overall though, most meals were okay, not bad, but not amazing either. They were better than store bought frozen food (although not Trader Joes, they still do frozen food the best). The two week plans actually last us closer to 3 weeks. As for the errors in the book, I didn't really notice them because I kind of fudged the specific amounts anyways. I don't have a food scale to measure out exact weights so I just guessed. If it looked like I was running low on something I added less, or if I had a lot left then I added more. With something like cooked chicken it didn't seem to matter much. Expect to buy a ton of food! For the two week plans my grocery bill was about $400. It would have taken me FOREVER to find everything at the store, but luckily I can order online and they bring it all to the house. Overall I like the idea, and might try a different make ahead cook book next time, since this one was hit or miss. Also note, my copy was new in 2012 and isn't spiral bound like the old ones, it would have been much easier if it was though!
