Best PB I've tried
I absolutely love this peanut butter. Without doubt the best I've tried. No, it's not 100% peanuts as the 1* review says but it doesn't claim to be, so that review is very unfair. Adding a little oil gives a smoothness and mellows the clagginess compared with brands that use 100% peanuts I feel. It's a personal preference thing. The oil in this is sustainable palm oil which is actually one of the most eco friendly of oils despite what Iceland will try and tell you.
It's not 100% peanuts
I thought it was all peanuts. Gutted when I read the ingredients. My fault but there's absolutely no need to add any oil to peanuts for any reason whatsoever.
