Daft question but did you craft it on another character?

Don't think it's been discontinued, but if you are sure it's that character your only choices are 1)Raise a Ticket in game, 2)Post in CS forum, or 3)forget it and seek out the recipe.

PS Provisioning is the easiest skill to level up, once you get a few level 20 and level 25 recipes (and ingredients obv) you can level it to max in a couple of days without even trying (just done it on a new characetr)

This is an L5 recipe, and that means if you don't have it, your only going to find it with an L5 ish character. So, if your like an L10 or so in character level, your going to have to buy it, or roll an alt to farm for it.

There are scads of recipes in the guild stores, and they sell quite cheaply, so you may have to do some shopping if you don't have it already.

You can also drop the quest, wait 20 hours and try for another recipe request. Although in my experience, the recipes tend to get repeated. Another thing you can do is level your provisioning some after you drop the quest so it is not asking you to make the recipes your character is leveled over. Provisioning levels real fast so it won't take much to do that.
