For anyone who already owns an Indian cookbook - and the place to start is Madhur Jaffey's encyclopedic Indian Cooking - this is a rich source of authentic South Indian recipes. I have tried most of them, and have yet to be disappointed. Be warned though, these recipes produce hotter dishes than most Indian cookbooks, and assume a basic familiarity with Indian cooking techniques. South Indian cooking is associated with vegetarian dishes, but this is Tamil cooking, and there are as many meat dishes as vegetarian, including beef, lamb, pork, chicken and duck. As for seafood, there are wonderful crab, lobster, shrimp and fish recipes. This is an excellent source of recipes for an underappreciated region of Indian cooking.
