Allied words after 150 LM is to go to the silver pine refuge in the gray valley to buy a book it.... The book is a good idea, it seems to be 90 silver, I forgot the exact name. The easiest thing to do is to go to the auction house and buy an intermediate cookbook, it won't be very expensive.

The Horde character level should be 35.

Cooking to 150 you can go to Burial Shadow Village and buy the book for advanced cooking, then you can get to 225

When you're a hotshot chef, come back and teach Zamza, okay? Departure!

Then he'll ask you to bring him 12 giant eggs, which explode when you hit the red statue under Garkisson, and 20 cheeses, which you buy in the South Seas, the one that's a level above the Storm City cheeses
