Hello Mate,
I had a Keralan friend pick me up a couple of books last time he was home. One of them is "Dakshin; vegetarian Cuisne from South India" and the other is "Recipes of the Jaffna Tamils" which also has an extremely large proprtion of vegetarian dishes in it. When I get a spare half hour I will type out the contents of the books and if you want a couple of the recipes I will post them for you.
Welcome to the group.
