Peanut butter is quite popular in the U.S., but as I understand it in many European countries it is an uncommon food. Is there any historical reason behind this, or simple chance?
You may be interested in this past question Why is it that peanut butter is so popular in America but not elsewhere in the world?
Also, putting on my modhat, having random Europeans check in just to say "I am from X, we eat peanut butter," is not a helpful comment.
