I've been trying to get into yakitori grilling for some time and thought this book would offer some good advice, while it did offer sources for equipment and some nice tips the overall package was a bit underwhelming.
For example the section on yakitori and yakiniku grilling recipes were all basically the same but spread out over many pages. The recipes itself were so stupidly simple that I didn't even need the book to tell me some of the things in the first place. This is one of those cooking concepts that only require you to read a few sentences to understand many recipes.
Note, finding red yuzu kosho is very difficult despite the fact that I myself, being Asian and living in a highly populated Asian area with many native Japanese, its nowhere to be found and even if I could find it its expensive enough as it is to use as a marinade for large amounts of food. I suppose if you are cooking for a tiny household and have a Japanese-sized appetite then it'd be economical but even using regular yuzu kosher is expensive and the author provides little alternative.
I feel the book is really dumbed down and in fact I feel patronized as a cook.
