We harvest GALLONS of wild Black Cap Raspberries each summer - sometimes Blackberries too, if we’re lucky. I freeze them, loose, on cookie sheets, then bag them and keep them frozen.
We eat them nearly every day on yogurt or cottage cheese.
I Picked 3 gallons of viking aronia, all frozen. Lots of antioxidants, but its not a really a tasty out of hand type of berry. I cut them up and use it to brew hot ginger / green tea.
The children are all grown and I have not been to the U-Pick blueberry patch in a number of years. The owner passed and I do not know if the Mrs. will continue the running the patch. I think that I will go this year and get 10 or 15 pounds to freeze if she is open.
