Why did Europeans never jump onboard the peanut butter train
In the US, there was this window just before petrochemical fertilizers, where the peanut was cheap, because it allowed the rehabilitation of land depleted by big cash crops. So peanuts were cheap, almost a byproduct. So poor Americans jumped at a cheap protein and vegetable oil source. It isn’t as if we developed a lot of recipes for it, but a peanut butter sandwich certainly became a cultural staple.
Why didn’t it catch on in a similar fashion in Europe?
