The cooking recipe Tasty Hatchling's Treat does not have a coordinate in ATT, however it is easily obtainable inside Valdrakken at 9.4, 55.5. Specifically it is contained inside a Barrel of Confiscated Treats.

Changing the recipe to be a reward from the object, with the object having the coordinates seems to be inline with how ATT generally handles such. Currently ATT simply states it is from a treasure in Valdrakken.
