Can I use olive oil ( Filippo Berio) that has been used during the year on Pesach, or do I need to buy a new one specifically for Pesach?
Also, is there a general rule that I can use to know what items from ‘year round’ CAN be used during Pesach and which ones I need to buy new?
Thank you!
Things that wouldn’t normally be contaminated with Chametz are OK.
I think olive oil is a good example. I imagine it’s unlikely any other food got into the olive oil bottle. On the other hand, there’s a pretty big chance you’re going to find bread crumbs in the butter you use with toast. etc…
