Enjoyed this book quite a bit. Like many I bought it as the companion book to the great series on Public Television. The first thing I would note is that the photography is incredible. Probably the best photography since that in the incredible K-Drama "Jewel in the Palace/Dae Jang Geum" (available on Amazon and a Korean foodies dream). It is not the definitive Korean cookbook. However, it is still an excellent source which is particularly valuable for it's explanation of and discussion of Korean ingredients. Some have criticized the book because Marja benefits from the perspective of her chef husband, Jean-George, and because she includes some of his recipes. For me this is a strength of the book. Viewing Korean cuisine through the lens of a classically trained French chef adds to the understanding of both cuisines.
My own perspective is colored by that of my Korean born wife. While Marja is from Uijeongbu in Gyeonggi Province, my wife was from a village near Mokpo in South Jeolla Province. I point that out because there are significant differences in Korean cuisine depending on the province where you were raised. Marja's discussion of kimchi making is a bit too simplified for me. Making kimchi is more than a science and more than precise measurements. How much kochukaru(gochugaru in Marja's rendition) used, for example, should be varied by the quality of the kochukaru. But, then I might expect too much. But to call Korean red chile powder, kochukaru, "ubiquitous" is to deny the many differing grades of kochukaru and the keen discrimination required to find superior grades. The selection of kochukaru alone deserves a full chapter.
Another slight quibble I have is with her discussion of the making of basic cabbage kimchi which she calls the "Ultimate Cabbage Kimchi." Ah, that is just flat pretentious. Women in Korea spend years learning how to make kimchi. It is properly prepared in stainless steel bowls, not a stinking bathtub! (Yeah, I understand that may have been an attempt at humor.) Also, her prescription of how cabbage should be salted and wilted does a disservice to the art of making kimchi. Proper wilting is determined by feel and it takes years of practice. Kimchi that is too wilted is very poor kimchi. Additionally, too little attention is paid to the the ingredients that go into kimchi.
But, in her defense, Marja is trying to sell a book, a cuisine and a culture and a little hype is essential to the process.
Finally, to her credit Marja does something I have not seen done in other Korean cookbooks. She discusses soju and makgeolli. The discussion would have been even better if she had discussed bekseju.
Don't let my Korean food snobbery dissuade you from this book though. As Marja notes at the onset, these are recipes from a Korean American kitchen. And, her American side thinks in terms of how many tablespoons or cups of this or that are required. (We Americans are too often anal like that.) Classical cooking in Korea was defined not by precise measurement by by the number and quality of ingredients. My wife, for example, thought in terms of numbers of ingredients then adjusted to the quality of those ingredients and taste. For example her kalbi marinade had five or seven ingredients. And, was she ever picky about the quality of her sesame oil and fish sauce. Maybe I'm just too picky myself because I know I will never probably never eat Korean food as good as hers again.
