About the organic or all natural peanut butters...
If you look at the label, they all should have only one ingredient... peanuts.
With no additives, the ability to change the taste of a peanut is frankly pretty limited.
IMHO, if you were to taste test these against their trans fat carrying friends and throw in a third sample of the organic with a little salt added, you'd get more people choosing the organic with salt.
Try it... I think it makes a big difference in the taste.
