Draenor Cuisine

If you want this achievement, you should also get The Draenor Gourmet.
This comment lists the total amount of materials required to cook for both achievements.

Or well, just buy the food from other players.

If you want the Draenor Cuisine achievement, and dont want to spend alot of money on AH buyind the ingredients you can farm them. In this post I will tell you where I had the best luck farming and how many of each you wil need.

For the little meals, with only one ingredient:
From flypoint Joz's Rylaks, Nagrand, follow the river down to the round isle of Ancestral Grounds, you can farm these following ingredients:
Riverbeast Meat you will need 30 of these to make Braised Riverbeast
Raw Clefthoof Meat you will need 30 of these to make Clefthoof Sausages
Raw Elekk Meat you will need 30 of these to make Hearty Elekk Steak
Raw Talbuk Meat you will need 30 of these to make Pan-Seared Talbuk
the reason why you need that many ingredients, is because you will need 1 meal to eat, and 5 to make the big meals.

To the west and south of Bladespire Citadel in Frostfire Ridge, around the two mountains, you can farm:
[Raw Boar Meat] you will need 30 of these to make Blackrock Ham

On the isle Darktide Roost south in Shadowmoon Valley, you can farm:
[Rylak Egg] you will need 30 of these to make Rylak Crepes

As for the fish you need to fish, you can get them these places:
Enormous Fat Sleeper around Nagrand's rivers. You will need 60 flesh to make Fat Sleeper Cakes
Enormous Fire Ammonite around Frostfire Ridge in lava, can be difficult to see. You will need 60 flesh to make Fiery Calamari
Enormous Jawless Skulker around Gorgrond's rivers and lakes. You will need 60 flesh to make Skulker Chowder
Enormous Sea Scorpion around Spires of Arak's coast line. You will need 60 flesh to make Steamed Scorpion
Enormous Abyssal Gulper Eel around Spires of Arak's rivers and lakes, especially in the river up to Shadowmoon Valley. You will need 60 flesh to make Grilled Gulper
Enormous Crescent Saberfish around Shadowmoon Valley's rivers and coast line. You will need 65 flesh to make Grilled Saberfish and Saberfish Broth
Enormous Blind Lake Sturgeon mostly around Shadowmoon Valley's rivers, but can also be found by the coast line. You will need 60 flesh to make Sturgeon Stew
NOTE: Each 5 stack of enormous fish, will give you 20 fish flesh.

I had 1 in dreanor cooking with the only recipes Blackrock Ham and Saberfish Broth, while I cooked these, I got new recipes for the ohter ones that I needed to do this achievement. So just start cooking. :)

For the big meals, with other meals (them above) and flowers:
