It seems that as a kid we we're always picking something - early in the spring it was fiddle head ferns, then late spring brought on the strawberries, and finally the summer brought huckleberries and blueberries.

1/2 cup sugar
1/4 cup flour
2 Tbsp. lemon juice

In 12 x 8 baking dish, mix well blueberries, sugar, flour, and lemon juice. Prepare Streusel Topping; crumble mixture evenly over blueberries. Bake at 375 degrees for 45 minutes.
