I love to shop at Costco for their cheap gasoline and awesome berries!
Usually you would see a container of blackberries as well; but they were out.
You can make this pie with only one type of berry if you like, or mix blueberries, raspberries, blackberries and strawberries. Since these berries are juicy and I've rinsed them thourghly with water, I like to use tapioca and cornstarch to keep the texture of the fruit filling firm and the juices contained around the fruit. You could use these same measurements for sliced peaches or possibly plums.
1 cup of sugar
2 Tbs. cornstarch
3 Tbs. quick-cooking tapioca
6 cups of washed and dripped dry blackberries,
blueberries, raspberries and quartered
1 Tbs. salted butter
1 deep dish Pie Crust
In a large bowl, mix together the sugar, cornstarch and tapioca. Add the berries and toss with your hands until the berries are evenly coated.
Pile the berries into the pie pan. Be sure to dribble the juices and mixture onto the fruit, then dot the surface with the butter. (this recipe actually filled 2 deep dish pie crusts)
If you're making your own crust, I would cover the berry mixture with a top crust and cut slits in the top to let steam escape during cooking.
Heat the oven to 400 degrees while you chill the pie(s) in the refrigerator for 15 to 20 minutes.
Put the pie(s) on a baking sheet to catch any drips and bake in the hot oven for 15 minutes. Then reduce the temp. to 350 degrees. Continue baking until the crust is golden and the berry juices are bubbling through the vents - about 50-60 minutes.
Cooling completely allows the filling juices to firm up. If you prefer, you can serve the pie while it's still warm with ice cream or whip cream on top. Which ever way you serve your Awesome Berry Pie, you'll enjoy! We love our berries raw or cooked.
