CRUST:

Add flour and salt to food processor

Add the pieces of cold butter and mix for about 10 seconds or until mixture is a coarse meal texture.

Add ice water a very little bit a time through the feed tube while food processor is running until dough holds together but is not sticky or wet.

Empty onto a large piece of plastic wrap, press together to form a dough ball.

Cut in half and form each into a round disk and wrap each separately in plastic wrap.

Chill for at least an hour.

When ready roll out each disk onto a floured surface, must be about 1/8 inch thick and fit in 9 inch pie plate. Place one disk in the 9 inch pie plate. The second rolled out disk can be cut as desired for a decorative top crust.

FILLING:

Pre heat oven to 375 degrees F

Move oven rack to lower 2/3 of oven.

Place cookie sheet in oven to heat it up as you prepare the filling.

In large bowl add in the berries, sugar, lemon juice and cornstarch.

Mix to coat berries thoroughly.

Roll out your bottom pie crust, place into 9 inch pie plate. Gently press into plate so to make sure it is laying flat.

Pour filling into pie, spread evenly.

Place pie dough strips over the top of pie and crimp edges together.

Place butter pieces on top of pie filling randomly.

Brush egg white on top of pie dough strips, sprinkle with sanding sugar.

Place pie on hot cookie sheet and back 1 hour and 10 minutes.

At 45 minutes check your crust, if edges are browning fast you can cover the edges with aluminum foil to prevent from burning.

Let pie cool completely.
