Well, we were using the gallon size Ziploc bags, and had 5 of them packed so tight we had to pour out a few from each bag so that it would seal. Was it a true 5 gallons, maybe not, but it was dang close. We really like blueberry scones, bb&lemon tarts and pancakes. Hey, it's a long winter up here and store bought berries just cannot compare to those ripe on the vine. Mother Nature provides us will all kinds of tasty morsels, even if they don't have a coat of fur or feathers. The salmonberries (which we ended up with more than 10 gallons) have been rendered to jams and jellies. The cranberry crop this year doesn't seem as abundant as in the past few years, but hopefully we'll get enough for sauce for Thanksgiving.
On a side note, our blueberries are no where near the size of the ones in Maine. Ours are considerably smaller and just a bit more tart.
