It isnt that old but it has these little pearly grains in it. They arent just on the surface, as we can see them if we look on the bottom of the jar. Any idea what this might be? Should we just toss it?
It has been some time, if anyone else has this problem:
Hold off eating it.
I would contact the company. They may have more information about the product grains. I have never experinced grainy texture in the Nutella. Their email address is: consumercare@ferrero.com.
It sounds to me like the sugar may have crystalized. If so, it's completely harrmless and heating it in a water bath will dissolve the crystals. This happens frequently with products such as maple syrup and honey.
However, I agree that contacting the company is a good idea and I fully subscribe to the philosophy "when in doubt, throw it out".
