Betty has variations in this cookbook for peach, blueberry, cherry, and plum. Since I figured blackberries were similar enough to blueberries I went with that variation
½ cup sugar
1 tbsp cornstarch
4 cups blackberries or blueberries or any berry I guess!
1 teaspoon lemon juice
1 cup all-purpose flour
1 tbsp sugar
1 ½ tsp baking powder
½ tsp salt
3 tablespoons butter
½ cup milk
INSTRUCTIONSHeat oven to 400⁰ Fahrenheit.
Stir together sugar and cornstarch in a 2 quart sauce pan and add berries and lemon juice.
Cook fruit mixture, stirring constantly, until the mixture thickens and boils. Allow boil for 1 minute.
Pour fruit mixture into a 2 quart casserole dish.
In a small bowl, mix together flour, sugar, baking powder, and salt. Cut in butter using pastry knife (or fork like I did) until mixture resembles cornmeal (crumbly).
Stir in milk and spoon dough onto fruit mixture.
Bake until hot, bubbly, and golden brown.
