Whole Earth tricked me for months.
The one ive found (and it is one) is by Meridian, the full range is here
(scroll half way down to find meridian stock)
they do it as 100% peanuts with or without added salt. this was available in a top uk supermarket that starts with the letters 'sai' and ends in 'urys' but about 3-4 weeks ago they seem to have stopped selling it. i did find it in a health shop in Wilmslow, Cheshire (fancy a drive) but otherwise its online im afraid. ive not ordered yet but im thinking a couple of kilo tubs will justify the price of postage.
can you tell ive had the same predicament? even h&b dont sell a healthy peanut butter (and their yoghurt coated range contains hydro veg oil), and this is the only one ive found so far.
hope that helps, if you find another let me know
