We have a next-door neighbor at our fishing camp who always gives us a quart bag of fresh blueberries every summer. I look forward to this wonderful gift each year so I can make this delicious bread. It has the texture of a cake and is very moist and delicate. I would check it at 60 minutes using the toothpick method - you may need to go a little longer depending on your oven. The berries do sink to the bottom so you may want to shake them in flour before adding to the batter.
