It's a cultural thing about peanut butter. Outside of North America, almost everybody in the world HATES the taste of peanut butter. And since my wife is from South America she also has that aversion. I think peanut butter is a taste that has to be acquired very young.
BTW, her idea of a better spread is Nutella which I tried and found to be horrible.
That’s interesting.
I’ve traveled internationally and have never noticed the absence of peanut butter!
I’m with you on Nutella.
