Be sure to wash them (gently) first, to let the Japanese Beetles float to the surface. The little boogers are hard to see on blackberries. I grow a 50 foot row of these wonderful fruits and they can take up a lot of freezer/container space. I like the smoothe idea to condense them. My grandkids have been making smoothe popcycles with the sour cherries and now the black raspberries and soon the blackberries. Its magic at Meme's house where snacks grow on trees!
