Ok, it's not like eating a huge spoonful of Skippy right off of the spoon, but it is a suitable substitute. It comes powered and you reconstitute it with water. 2 Tbsp peanut butter and 1 Tbsp of water is a good consistency for eating (1 pt).
I order mine directly from here, Bell Plantations
they also have a store locator so you can see where it is sold near you.
The packaging has changed, so mine doesn't look like the website, but it's the same thing.
