This is a pretty easy quest and is the only one that you need to leave Dalaran for to get mats. If you're Alliance you get
Sewer Stew from
Katherine Lee (41,65), the Grand Master Cooking Trainer in the kitchen of A Hero's Welcome. If you're Horde you get it from
Awilo Lon'gomba (70,38), inside The Filthy Animal next to Krasus' Landing.
The materials you need for this daily are 4
Crystalsong Carrots and 4
Chilled Meat.

You will find the
Crystalsong Carrots in Crystal Song Forest
right below Dalaran (around 29,42) near some ruins by the river. They look like giant carrots sticking out of the ground and, being a quest item, they sparkle. You need to run around and right click on them to loot them. Once you have 4
Crystalsong Carrots you cook them up with your 4
Chilled Meat to make
Vegetable Stew.
When you have your
Vegetable Stew cooked up you can deliver it to
Ajay Green at the Cantrips and Crows Tavern in the Underbelly. He will give you 9g93s, at least one
Dalaran Cooking Award and a
Small Spice Bag that can contain any, or all, of the following:
Northern SpicesOld SpicesBaby SpiceDalaran Cooking AwardAnd if you don't have it,
Recipe: Delicious Chocolate Cake. (This is a rare drop, 1.7%)
This is another easy quest, just remember to keep some
Rhino Meat and
Chilled Meat on hand, it makes these daily's go so much quicker.
Good Luck :)
