Pros: Well illustrated, well explained, thoughtfully laid out
It's much more than a collection of recipes. In this book Kenji explains cooking techniques and the science behind them. Also ingredients and how to find them, how to use them.
For many recipes, there is a fully illustrated 'knife techniques' section. ex. for people who are not pros, it is very useful to explain how to cut up a fennel or any other uncommon or oddly shaped produce.
