Used all the damsons (a gift) to make jam, sadly no gin!
Couldn't understand why jam made with 'beet' sugar was less successful, chatted to my neighbour also a jam-maker (she once lived near Tiptree!!!) who said not to use it..... did she have insider information, I wonder?
Have never tried butters but my old, reliable preserves recipe book has recipes for butters, cheeses and pastes! I'm put off when I read that their 'keeping' qualities are poor!
Damson was my Dad's favourite too so the whole 'jamming' business takes me back.
Memories of picking blackberries with Dad, an ambulance driver who noted good spots as he drove around, altho we never picked from roadsides even when there was hardly any traffic. Sadly I don't have my Mum's old jam pan, it was extremely heavy, I seem to think it was brass. Later she used a large aluminium catering pan ( the sort seen in old school canteens!) I didn't want that one! 
Now why am I having trouble posting this?
