Master of the Grill

Lets begin at the beginning; In order to obtain this Achievement we first need to have a [skill=185] level of 530. There are plenty of guides explaining how to get there, so I'm not going to repeat them here. Once we have obtained 530 in cooking, we then must proceed to [npc=64231] who is found at Halfhill in the Valley of the Four Winds, next to [npc=60231] allowing for easy access.

[npc=64231] is a [skill=185] Trainer, who has recipes that allow you to obtain 530 if you're not quite there as well as selling the ingredients needed for those recipes. She offers a total of 9 quests, only three of which we have to worry about for this Achievement.

1) So You Want to Be a Chef...
Simply buy 5x Pandaren Peach, learn Sliced Peaches and cook them. Hand them in and get the next quest:
2) Ready for Greatness
Simply buy 5x Rice & 5x Yak Milk, learn Rice Pudding and cook them, upon completing this quest the 6 "Way of..." quests become available, we want Way of the Grill for this Achievement.

Way of the Grill requires that we hand in 5x Raw Tiger Steak to [npc=58712] who is located within the 'circle' of Cooking Masters to our right when facing [npc=64231]. Upon completing the quest, [npc=58712] will return our Raw Tiger Steak and present us with a new quest: [quest=31467]; First we have to learn the recipe [spell=104298] from [npc=58712] and then cook 5x [item=74642] before presenting it to him.

Now we are into the unguided section, there are 5 Grill recipes, only 3 of which are needed to hit a skill of 600. Given the easy of obtaining Ironpaw Tokens, I shall be referring to them in this guide.

Obtain 15x Raw Tiger Steak and make [item=74642] until skill 550.
Return to [npc=58712] and learn Eternal Blossom Fish
Jade Lungfish can be Fished or bought with one Ironpaw Token from [npc=64395] who sells [item=87721].
Striped Melon can be Looted, Harvested via Striped Melon Seeds or bought with one Ironpaw Token from [npc=64395] who sells [item=87714].
We will need 6x Ironpaw Tokens to buy 3x [item=87721] & 3x [item=87714], make [item=74645] until reaching a skill of 576, this should only mean making 13, but mileage may vary. Extras can be stored or sold, what ever you wish to do.

Return to [npc=58712] and learn Banquet of the Grill
Redbelly Mandarin is Fished or Bought via [item=87724], Raw Crab Meat is Looted or Bought via [item=87704] and White Turnip is Looted, Bought via [item=87716] or Harvested after planting White Turnip Seeds.
100 Year Soy Sauce can only be obtained via Ironpaw Tokens.
We will need 5x 100 Year Soy Sauce, 50x Redbelly Mandarin, 50x Raw Crab Meat & 250x White Turnip that is a total of 35x Ironpaw Tokens, we should only have to make 5 lots of the Banquet of the Grill (5 per lot) to hit our goal of 600 skill points in the Way of the Grill.

We will have used a total of 41 Ironpaw Tokens to go from 530 to 600, but you may reduce this number by Looting your own ingredients or Harvesting them on your own Farm.

Materials Needed:
_25x Raw Tiger Steak -Vendor Bought with Ironpaw Tokens
__5x 100 Year Soy Sauce -Vendor Bought only with Ironpaw Tokens
_65x Striped Melon -Vendor Bought with Ironpaw Tokens, Grown with Striped Melon Seeds or Looted
_13x Jade Lungfish -Vendor Bought with Ironpaw Tokens or Fished
_50x Raw Crab Meat -Vendor Bought with Ironpaw Tokens or Looted
_50x Redbelly Mandarin -Vendor Bought with Ironpaw Tokens or Fished
250x White Turnip -Vendor Bought with Ironpaw Tokens, Grown with White Turnip Seeds or Looted

With all luck, we should now have this Achievement and be considering how to work on the other five; Master of the Wok, Master of the Pot, Master of the Steamer, Master of the Oven, Master of the Brew to finally gain Master of Pandaren Cooking and the title [title=315].

Happy Cooking

If you are pandaren you need to obtain 615 skill points in the Way of the Grill to get this achievement.

To save time/mats make [item=74642] till 550 then make [item=74645] till 576 then make 3 Great Banquet of the Grill , going to 551 with [item=74642] will mean [item=74645] will go grey at 575 meaning you will need to make 5 small or 4 large feasts to max your Way of the Grill.
