Blackberry Roll

From Diana Rattray,
Your Guide to Southern U.S. Cuisine

2 cups sifted flour
3 teaspoons baking powder
1 teaspoon salt
1 tablespoon granulated sugar
1/4 cup shortening
3/4 cup milk, more or less
2 cups fresh cleaned and sliced blackberries
3/4 cup granulated sugar
1 tablespoon butter, cut in several small pieces

Sift together the flour, baking powder, salt, and 1 tablespoon sugar. Cut in shortening until mixture resembles meal. Add enough milk to make a soft dough. On a lightly floured surface, roll dough out into a 1/4-inch thickness. Spread with blackberries to about 1/2-inch of edge. Sprinkle 3/4 cup sugar evenly over the berries then dot with the butter. Roll up like a jelly roll and seal ends. Place in a greased shallow baking dish. Bake at 425° for 25 to 30 minutes. Serve with cream or whipped topping.
Serves 8.
