MMMMMmmmmmm that sounds fab! I am planning a blackberry raiding session over the weekend as there are so many fields here full of ripe blackberries.
It'd be rude not to...
Will have a go at blackberry jam (never made jam before) and might give the ice cream a go too if I get enough - although I'll have to look up traditional ice cream making as I don't have an ice cream maker. Looking forward to it already
