Cooked berries appear to be easier for the elderly to consume. I put them in at the last minute and watch them swell while cooking, some burst to release the wonderful color and aroma into the cooking pancake.
I grow blueberries in my garden. One needs to plant different varieties to get berries. I have three blueberry varieties growing in my yard that produce a couple handfuls of berries each year. Once ripe, I pick them quickly.
