On arriving in Fenny Stratford on the Grand Union, we discovered that we had moored next to a bumper crop of blackberries. These berries were fat glistening jewels of spectacular quality so we set about picking with enthusiasm.  Just 30 minutes later we had enough for several batches of Blackberry Wine jam and therefore the next couple of days was mapped out for us.  This jam is cooked in red wine and then has more added just before potting so it's a delightfully boozy treat.  Perhaps not surprisingly, it is one of our most popular jams!
