It is better to download books online than to buy them. There are many kinds and easy to access. "Cooking book download", "recipe download", "cooking introduction download", "recipe download", "Japanese cuisine download" all have very good e-books. Although printed books are easier to read, the content is relatively thin, and it is difficult to find several satisfactory ones in one place. For easy-to-use recipe examples, I suggest you check out Tiantian Food Network, which has video tutorials. Much better than reading a book.
