50 Cooking Awards

The Dalaran Cooking Award obtainable through the Dalaran daily cooking quests, you can get 1-2 awards as quest reward and occasionally +1 from the Small Spice Bag.

Also worth of mentioning that the achievment counting the award at the moment you get it,so you can use them and don't have to own 100 at one time.Maybe it's a bit easier this way :)

there is also a chance to get 5 cooking awards from the fishing daily in dal. (you get a waterlogged recipe in the bag obtained, and turn it in for 5 awards.)

As per this blue post (and the green followup a few posts down), Dalaran Cooking Awards are now internally considered "currencies", or "points", whereas before they were "emblems" or "items", which just happened to be stored on the currency page and not in your bags. This switchover is why the Dalaran Cooking Award Achievements no longer progress, because WoW does not (yet) have any system for tracking the total accumulation of actual currencies other than copper/silver/gold.

This is also likely why additional Dalaran Cooking Awards no longer drop from the Small Spice Bag, because they are no longer an item, but a currency.
