And I say black nightshade :-)

Apparently, in New Zealand, they make jam from black nightshade.
As I have no good evidence that it is the same species, and the
Solanaceae's berries vary from the edible to the lethal, I am
not going to experiment. I am happy to take risks, of the sort
where I will merely regret my actions for a day or so, but this
is a different class of risk. If you eat a kilo of green tomatoes,
you may get bellyache; if you eat 100 grams of potato fruit, that
would be the least (and last) of your problems.

If anyone has DEFINITE and RELIABLE evidence that Solanum nigrum
has edible berries, I should be interested to hear.

Not evidence, but a reference:

George Usher 'A dictionary of plants used by Man' "The fruits
(woderberries) are eaten in pies etc. The shoots and leaves are used as
a vegetable" Blimey!
