Now I Am the Master

To get this achievement, you must buy a [item=86425] with 50x Ironpaw Token, and complete the apprentice [faction=1357]'s daily quests until you become Best Friends with him.

You cannot purchase it until you have completed the quest To Be a Master from [npc=64231] which involves cooking all level 600 meals from all 6 cooking specialisations.

Each friendship tier, he will offer a different quest:
Lesson 1: Sliced Peaches - Stranger
Lesson 2: Instant Noodles - Pal
Lesson 3: Toasted Fish Jerky - Buddy
Lesson 4: Dried Needle Mushrooms - Friend
Lesson 5: Pounded Rice Cake - Good Friend

In order to progress to Nomi's set of dailies you must complete the To Be a Master. You will then need 50 Ironpaw tokens to purchase a Cooking School Bell which will summon Nomi and begin the teaching of your apprentice.

Nomi has five friendship tiers each with something different for him to cook on a daily basis. To clarify you do not have to cook anything, all you do is give the ingredients and he will cook it himself.

Part one: 5 x Pandaren Peach

Part two: 5 x Instant Noodles

Part three: 5 x Golden Carp

Part four: 5 x Needle Mushrooms

Part five: 5 x Rice

you can purchase the mats for this right in the market, so no need to hit the AH or farm them. (thanks Mazhop).

Exalted? Done.
Everyone is your best friend? Done.
Master of the Ways? Done.

And just when I thought I was done with Halfhill... this comes up.
