That recipe sounds so good. and thanks for reply, no we put them in 2 gallon freezer bags and laid them on their sides to freeze. I really don't have a way to put a large cookie sheet in my freezer. So I guess that is where we messed up. I'll try your recipe and see if this works.I never drain them - I use them in the frozen state. Hopefully, you froze them on a cookie sheet so they are all loose berries, otherwise I guess you would have to thaw them to use them. Cobbler should be similar to pie so here is my recipe for blackberry pie. Recipe works for fresh berries as well.
In a small bowl, mix together:
1 cup sugar (I actually use about 3/4 cup, but that is a slightly tart pie filling)
1/3 cup flour
1/2 tsp ground cinnamon
Pour the flour mix over 4 cups of berries and stir to coat. Pour into pie crust, distributing the excess flour evenly through the berries. Top berries with 2 tablespoons of butter, cut into pieces. Put on top crust and seal edges. Make sure the top crust has slits on the top.
As the pie bakes, the berries thaw and the flour thickens the juices.
My husbands favorite pie - probably one of the reasons he married me. hum, let me think ... no, he never got blackberry pie until after we were married. Must have been the brandy slush and german potato salad after all...
