I made these this morning and they are really yummy! A definite keeper! I made a few minor changes....didn't use pastry flour. In the filling I used a 16 oz bag of frozen blueberries, so it was a bit more than 2 cups. I used about 3 T lemon juice, and in the topping I used 1/4 cup rolled oats instead of 3 T flour.
You may know this, but blueberries are rated #1 in terms of antioxidants of all fruits and veggies! So eat up!
