At the moment there are only two recipes available to learn from the cooking trainer. Fish cake (restores health and mana) and Pandaren meatballs (restores health). I managed to get a skill point every 1-3 Fish cakes but sadly, cooking the Fish cake only gets you to 530 before the recipe turns grey.
Cooking in Mists is tied in very heavily with The Tillers so if you’re serious about getting your cooking skill up, you’ll need to work on your Tillers reputation as well. Keep in mind that the dailies for The Tillers will only become available once you reach level 90.
