Sweet Berry Pie

For the pie dough:
1. Combine the flour and salt in the bowl of your stand mixer or food processor. Add the butter and blend with dough attachments until pea-size nuggets are formed. Add the water all at once and continue to mix until the dough comes together.
2. Pour dough onto a sheet of plastic wrap. Form it into a disc and wrap with plastic wrap. Refrigerate for at least an hour.

For the assembly:
Preheat oven to 420 F/216 C.

1. Divide the dough into two equal pieces and put one onto a lightly floured surface. Roll it out to 1/8 inch thickness and line the pie pan. Wrap the remaining dough with plastic and put it back into the refrigerator.
2. Combine the fruit, sugar and tapioca starch in a medium size bowl and gently mix until combined. Set aside.
3. Roll out the remaining dough to 1/8 inch thickness as well. Place the berry mixture into the lined pie pan and place the remaining rolled dough on top. Trim off the excess and crimp the edges together to seal the berry mixture into the crust. Use a sharp knife and cut a few vents on top.
4. Bake pie at 420 F/216 C until golden brown, about 45 minutes.
