2 pints blackberries
1/2 cup water +1/2 cup water
1 1/2 cups sugar + additional sugar
3 cups flour
3 teaspoons baking powder
1/2 teaspoon salt
1/2 cup shortening
1 egg, separated (lightly beat, separately, the yolk and white)
Put the blackberries in a saucepan and add 1/2 cup water. Using medium heat, bring to a boil. Then reduce heat and simmer until the berries are very soft; stir periodically. Remove from the heat and press the cooked berries through a sieve. (I used a Foley mill.) Rinse out the saucepan, then put the strained pulp back into the pan. Stir in 1 1/2 cups sugar. Bring to a boil using medium heat, then reduce heat and simmer until the sauce thickens while stirring periodically (about 20-30 minutes). Remove from heat and cool.
In the meantime, Preheat oven to 425°. Sift together the flour, baking powder, and salt, then cut in the shortening. Add beaten egg yolk and 1/2 cup water; mix using a fork until dough starts to cling together. If needed, add additional water. (If desired, a food processor can be used to make the dough.) Knead dough slightly then roll part of the dough into a rectangle 1/4 inch thick. Cut into small rectangles each about 4″ by 2″. Spread the cooled blackberry sauce onto the small rectangles, and then roll. (Reserve about a quarter of the sauce to use when serving.) Put on a baking sheet. Brush with egg white, then generously sprinkle with sugar. Bake until lightly browned (about 1/2 hour).
Serve hot with the reserved blackberry syrup that has been reheated .
