There have been reports of people who claim they found the recipe without having alchemy. 
Since the recipe drops only from a Canopic Jar with a 5% drop rate and the Canopic Jar can only be found With archeology on a RNG base and only in Uldum digsites that spawn RNG generated. you can be sure this is a very rare item.

I can confirm that alchemy is not even required to get this recipe. I have Engineering and Mining and the recipe dropped. I'm definitely not dumb enough to delete it and am seriously thinking about getting rid of Mining and leveling Alchemy just to learn it.
EDIT: Now that I think of it, why is this the only Arch epic not BoA? What if I had an Alchemy alt I didn't want to level Arch on? GJ Blizzard.
