Recipe:  Oregon Pioneer Blue Cake  (the berries make the cake blue)

Ingredients:

1 egg
1/2 cup sugar
1 cup flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 cup water
1 cup wild blackberries

Instructions: 

Beat the egg until thick and lemon-colored.  Slowly beat in the sugar. Sift
together the flour, soda, and salt then stir the flour mixture into the
egg.  Stir in the water.  Fold the berries into the batter.  Bake in a
greased square pan (about 8" by 8" is good) for 25 minutes at 350 F.
Sprinkle with sugar and cut in squares to serve.  This is good as a coffee
cake or warm with ice cream or topped with cream (that's like a pudding).
