How to safely home can blueberries with a touch of booze!
Start out with only a small amount of blanching water, just enough to cover the berries, because as you blanch the berries they will release juice and the amount of liquid will increase. That way, you end up with purer and less watered-down juice to use for packing the berries in.
Instead of brandy, you could try cognac, rum or vodka.
