I am basing this on absolutely nothing...except for a strange gut feeling. I just think that peanut butter, in all it's gourmet forms, both high and low, has potential as a new "it" food. It's got all the characteristics of one: it's readily available and everybody likes it, but there's tons of room for variation within the category. It's well-known and popular eaten on it's own, or as the central ingredient in something, but it's also a useful supplementary ingredient in a number of other recipes.
I really can't explain why, but I definitely expect to see a lot more artisanal peanut butters pop up soon. Peanut butter for everybody this Christmas!
