I must admit I originally balked at the price, but I bit the bullet and bought it and have not regretted it. The app is incredibly detailed and covers darn near anything you could realistically want to do in your kitchen. The pictures rival Williams-Sonoma in quality and detail (which are renowned). Theres a reason this was rated one of the top five culinary books of the decade. If you want to learn how to cook, this book/app is hands down, the best on the market.
My one caveat, the portions are somewhat larger because (IMHO) the target audience isnt Mom or Dad making dinner for a family of four on a Friday night so take this into consideration.
