Morning all.
I use cheese cloth and strain my blackberries when I want to make jam from them. Makes a world of difference. Neighbor gave us a jar of their blackberry jam, unstrained, and every time I ate any of it I was picking seeds out of my teeth for days. What is real agony is getting one under a partial plate or bridgework, both of which I have. It makes me jerk out the partial REALLY fast and as for the bridgework, I'm just flossing under it till the offending seed comes out.
While I love berries, blackberries are not high on my list as snack food. Pitiful since we have about 100 plants. Rotten crop this year. They all froze off at the ground last winter so all of this year's canes were destroyed. New growth did fill in but the few berries we have are sour and have hard spots in them. The birds are loving them as are the chickens!
