Blackberry Cobbler

I adapted this recipe from a Taste of Home Recipe to use clear jel along with a few other changes.  Served it at Garden Club tonight.  Everyone loved it.  

Blackberry Cobbler
1/2 cup sugar
2 T. Instant clear jel or Tapioca
1/2 t. cinnamon
5 c. fresh or frozen blackberries, thawed
1/4 c. orange juice
DOUGH:
1 c. flour
1/3 c.sugar + 1 T. for topping, divided
1/4 t. baking soda
1/4 t. salt
1/3 c. sour cream or vanilla yogurt
1/2 t. vanilla
1/3 c. milk
3 T. butter, melted
In a large bowl, combine the sugar, clear jel and cinnamon. Add blackberries and orange juice; toss to coat. Let stand for 15 minutes. Spoon into a 2-qt. baking dish coated with cooking spray.
In a large bowl, combine the flour, 1/3 cup sugar, baking soda and salt. Combine the sour cream, milk and butter; stir into dry ingredients until smooth. Spread over the berry mixture.
Bake at 350° for 20 minutes. Sprinkle with 1 T. sugar. Bake 20 minutes longer or until golden brown. Serve warm.

Can use with other berries or even peaches.
