This book has everything it needs to pass as great to the majority of the population; glossy photos, cute names, and it's about sushi.
Very trendy.
As a Vegan, I was not as impressed. The stock recipes include bonito (dried fish), and offered no substitutions for it. Several of the recipes called for the stock, or water. Water doesn't add any flavor to food, obviously. So it's either fish, or a substandard dish. The author also includes seafood suggestions on nearly every page. The last time I checked, fish are living creatures. Fish are not vegetables.
I expected a few mentions of egg or dairy, it is a supposedly Vegetarian book. But I can't say I expected flesh to be involved in the cooking process.
Before becoming Vegan, I had never eaten sushi due to my allergy to seafood. So if you have a similar allergy and are looking to enjoy Sushi, I would recommend searching elsewhere.
