Cooking awards question.

So, once you've bought all the dalran cooking recipes is there any reason, at this time, to keep dalran cooking awards?

I know you can spend them on northern spices, but with doing the daily I've got a stockpile of over 100 and I've sent a couple dozen to the AH. I know they could always add in a new recipe or whatnot but I figure there would probably be some advanced notice. I assume the usual route is buy spices with them and use/sell northern spices depending upon need?|||100% correct.

I was using spices to help level cooking on my alts. But then i use spices to make food for raid and sell surplus.
