Plum Blackberry Streusel Pie ~Beneath a humble, oaty streusel topping lies a sleek, inky jumble of plums and blackberries—talk about a delicious contrast. A combination of cornstarch and tapioca in the filling helps to keep the colors of the fruit true and to set up their juices nicely from becoming too thick. The aroma that permeates your home as this pie bakes is so full of the wonderful fruit essence you will have a tough time letting it cool. Don't put it out on the stoop or you may be inviting visitors that will want to share a slice or two. Whip up some of my Blackberry Chocolate Frozen Yogurt to top off this gorgeous dessert!
