yep, frozen is fine! fresh ones hold themselves together better and have a better flavour but frozen is what we use too in the off season. have you got room for some bushes? we have 4 blueberry bushes, but have a pretty large edible garden. they haven't produced so well for the last two years but i think it might be all the moving around we've done as before that we'd had them probably about 6-7 years and they have been prolific every year. either that or they're feeling a bit root bound... should probably plan them out now but haven't got around to it.

just like frozen fruit is great in say muffins - frozen apples and fresh cranberries.... yum! and then you can put in just a fraction of the sugar (as well as).
