not cooking the berries, just the pectin. So it ends up being blanched berries preserved in much sugar and a freezer. Too sweet for my taste but it does make a jam.The butter is added to keep the foaming down.... if you have to go through all the effort to cook the fruit, why would you freeze it?

Ok back to work. I do not answer chicken questions because I do not have chickens. If I could help I would!
