I have never tasted blueberries until one day my hubby ordered a fruit cake from whole foods . I loved them. They are tangy, like raspberries, but they have a unique flavor and cannot be compared to anything else. Some of them are sweet. I am a big fan of fruit cakes . They are so fresh and sinfully delicious. I researched for many recipes using these berries . I love streusels on cakes and pies. A streusel is a crumb topping of butter , flour , cinnamon and sugar that is baked on top of cakes and muffins.I used them as a topping on my cake too.
I made a three layer cake in which one layer was white cake , second was fresh blueberries and third was streusel . I used some store bought blueberries , one large egg (At Room temperature) and a cup of butter (At room temperature). It was just awesome .
