Yet another dessert - only one more after this, I promise :)
The store had a buy 1, get 2 free sale on blackberries, so this is the result. I found this recipe on allrecipies.com, and made a few changes as per the comments. Hopefully it tastes as good as it looks.
Update: It did. If not better.
4 C fresh blackberries
1/2 C white sugar
1/4 C instant tapioca
A 9 inch double crust pie (store bought, I didn't have the patience for a hand made one)
Place the bottom crust into pie pan, brush with a little bit of egg or eggbeaters (this prevents the crust from becoming soggy). Combine 3 1/2 cups berries with the sugar and tapioca - mix until there are no clumps of white anymore, all dry ingredients stick to berries. Spoon the mixture into pie shell.
Spread the remaining 1/2 cup berries on top of the sweetened berries, and cover with the top crust. Seal and crimp the edges. Brush the top crust with egg, and sprinkle with sugar.
Bake at 425 degree F (220 degrees C) for 15 minutes. Reduce the temperature of the oven to 375 degrees F (190 degrees C), and bake for an additional 20 to 25 minutes.
