Recipe for vials for alchemy?

A few weeks ago, I saw something about a recipe coming with the new patch for alchemy vials, where 5 Rank 1 vials could be converted to Rank 1.

Where am I supposed to get the recipe? The renowned quartermaster of the new faction doesn't sell anything like that; he sells many other recipes, but not this one. Did they not add the recipe at the end, or am I completely lost?
