Had to kill the Sharptalon Matriarch twice in order to see the orphan.
The orphan waits on a hill almost right next to his mama at 46.94 10.73.
You can buy the needed food in Dalaran - no need to fly around to pick it up.
The Aszunian Grapes are sold by Applebough - the treant right to the alliance inn.
You can buy Pungent Vrykul Gamalost and Dried Bilberries from Fialla Sweetberry in front of the shop for cheese & wine.
Amisi Azuregaze,the innkeeper at the neutral inn in the middle of Dalaran sells Smoked Elderhorn.
Hope it helps
