* For the blueberries, I froze fresh blueberries and used them in the batter frozen. If you want to follow the wise words of Ina Garten, toss the blueberries with some flour before incorporating them into the batter. This will prevent the blueberries from sinking to the bottom of the pan while baking. I did not sprinkle with flour, ergo my blueberries sank, but that was fine with me.
