When you are making a cobbler, one of the most important things that you can do in order to ensure that it tastes great is to be picky about the berries that you choose to use. Most recipes will call for fresh blueberries.
The reason for this is because fresh blueberries have the most flavor. In addition, frozen blueberries often will lose their flavor, texture, and color during the freezing process. Even if you thaw the frozen blueberries, they are just not going to bake as well as fresh blueberries. When you go to the market to get your blueberries, look for ones that are bright and juicy. Make sure that you are picky about choosing your fresh blueberries as this is what is going to provide your dessert with the most flavor.
Take your time and choose only the best. This is one of the reasons that blueberry cobbler is best to make when these berries are in season.
