>>> I don't know really what "Amazon recommendation " means either
If you're referring to the link in Allen's post, Rosie, it's just something that AB's server is configured to do. ANY link to Amazon UK that's posted here is
automatically replaced by the wording that you can see. (Even if someone posted a link saying "Look at these really appalling reviews", you'd still see it replaced by the 'Recommendation' bit). I suspect that it's set up that way because some Amazon links can run to hundreds of characters.
The purchase that Allen is thinking of making looks ideal to me if he intends to be doing quite a bit of chopping and grinding. (Ruddy 'eck! That sounds like a euphemism for something naughty!). However for just a bit of occasional spice grinding, a coffe grinder might do the job just as well:
