I bought a 3L tin of OO for 11.99 at the grocery store. It said imported from Italy, thought it was a great deal. Once I got it home and opened it, it smelled very sweet, but not a nice sweet smell IMO, completely different from any other OO's I've smelled before. I made 2 bathches of soap with it. The first one was with peppermint EO, worked out great, but the second was with a FO, and it totally morphed and the smell of the soap really stinks to me... could this oil be expired, and sabotaging my soap?
