Is this pesto molding?

On Saturday we decided to have a quick pasta of pesto spaghetti. We roasted all  the veggies that we had been neglecting in the bottom of our fridge. The pasta had been boiling for about 5 minutes when I pulled the jar of pesto from the fridge.
Is this pesto molding? Mike and I deliberated. The part on the sides of the jar, near the lid, looked white. I assumed this was because the oil was slightly frozen. Further down the sides it got much darker. Was it just dry? Did the rest look fine? What if we just stirred it? Maybe we should try a bit before we ruin the pasta? Mike dipped a finger in and decided it was fine. I decided that if it took longer to conclude than a UN debate on the definition of 'gender' then we probably shouldn't eat it.
Good thing everything is ready and we have no sauce. To the mini food processor! I wheeled around the kitchen grabbing things that could be in a pesto. One clove of raw garlic, few spoonfuls of sun-dried tomatoes (packed in oil), parmesan (mine comes from a can, sadly), fresh basil (okay fine, I only have dry basil. It`s March!), pine nuts (yeah I didn`t have any of those either), few tablespoons of olive oil. Blend. Add lots more olive oil when you realize you`ve made a paste, not a pesto.
Tah da!

It looks gross here. I probably should have taken a picture of it on the spaghetti, all glistening and such. Oh well. Also I would like to take this time to formally apologize to Mike for waiting for him to eat the jar pesto before declaring it unfit. Will you forgive me NOW? Yesh. Holds a grudge.
