Hm. Apparently, the good grocery, in addition to making the good, cheap 100% peanut paste, also makes a form that's only 90% peanuts, with the usual fillers of oils and sugars, and this is in a very similar jar, and is occasionally mis-shelved with the other. S'alright, perhaps I needed the sugars and the oils in the diet.
