Crazy question but blackberries are out of season now and lots of people are
requesting bb jam----can I use frozen ones ir I can find any? Thanks!

Our blackberry season here in the Southwest is fickle at best. Our local grower
freezes most of her batch and I've never had any problems using them for jam.
BTW - about 1 pound is 1 dry quart is about 4 measuring cups mashed. Best of
luck.
