My money's still probably on bruising: see at http://www.potato.org.uk/department/knowledge_transfer/pests_and_diseases/ref.html?item=33 That looks like it! Bruising. Hmmm. Looks like someone hasn't been very careful harvesting the potatoes. I've only seen this on shop bought potatoes, never on my own. -- David in Normandy.

I've just received vouchers for 2 more packs of the potatoes I complained about. It will be interesting to see if they turn out to have the same defect. Graham |

As I mentioned the other day, I suspect it's a consequence of commercial handling. -- Mike. |
