I just put several quarts of huckleberries in the freezer last night. No canning, exactly, but that's the best way my family has found to store them long-term. Rinse and drain them thoroughly, put them in clean jars with lids very tight, and put them in the freezer. They will last for several years, and only leech a little bit of that huckleberry scent/flavor.

I belong on eroding granite, among the pines.
