Had 3 cups left over, not quite enough for my favorite pie dish, so sweetened a bit with raw sugar, added 1/4 teaspoon of cinnamon and cooked it into ice cream topping. Yet another way to serve them. I go 1/4 cup sugar per cup of wild (trailing) blackberries for a tart taste.

OK. I over focus. And berries are my focus this week.
I actually like the raw fresh berries on ice cream better than this cooked sauce but my wife prefers this.
