Would you eat Pesto , that had been opened for a few weeks and not in the fridge????

Dh says it will be fine.

Hmmm

Nope.

I would expect it to be growing actual mould under those circumstances. If it wasn't I would probably eat it, but wouldn't serve it to guests.

Absolutely not!

No mould, smells fine.
Might be a week, can't remember...

depends

freshly made by your own hand = no
jar packed full of preservatives = yes

but would keep it in the fridge next time

No way.

If it wasn't mouldy, then yes.
