Hello. I have a quick question about an Iranian product. I purchased some dried, powdered kashk. I have had it stored unrefrigerated in my cellar. Does anyone know if it can expire? Should I store it in the fridge? Thanks! Kheili mamnunam!
As long as it is dry, it should be fine. If there is any weird smell (other than the overly strong flavour of kashk) then I would not eat it. If there is any mold growing, I would not eat it.
Most dry products do not really expire. Bacteria and Mold can't grow on them because they do not have enough water to live.
I would store it outside of the fridge in a lidded container in a dry area.
