Spoilers listed below. Highlight test to see
If I remember correctly, there were at least 3 craftable pets. One was I think a scorpian, gargoyle's pet and something else. There is a quest giver named Sutek that gives the quest to obtain these recipes. Unfortunately I cannot find Sutek since the open beta because there used to be a moongate directly to Sutek but I can't find it anymore. Anyway, these pets are craftable by tinkers, not cooks.
I think there are some new food recipes that give buffs, obtained through quests.
