My childhood memories are pretty dim, but I remember this for some reason. The man grated some carrot very fine (like the cheese, above) and made a dressing with cider vinegar and honey. We liked it. I have no idea what this cost her, but she bought it.
Unfortunately, it takes up a lot of space and storing it was awkward - she rarely used it.
Right now I've got it in a perfect sized box in a corner of the living room, and I'm really hoping that when the cabinets are purged there will be a space for this treasure.
