How to Make a Raspberry Pi

If this article made you hungry for some of this Raspberry Pi but it sounds really expensive why don't you make one of your own?

REQUIREMENTS:
1  cup plus 3½ tbsp. sugar
¼  cup cornstarch
1  lb. raspberries
1 tbsp. fresh lemon juice
2  9-inch pie shells
1  egg

SETUP GUIDE
Preheat oven to 425 degrees.
In a small bowl, whisk together 1 cup sugar and cornstarch.
In a medium bowl, toss raspberries with lemon juice; add sugar mixture and stir to combine.
Place a pastry shell in a 9-inch pie dish. Add in berry filling. Top with second shell—either solid with slits cut in or woven into a lattice pattern—crimping edges with your fingers or a fork to seal.
In a small bowl, gently whisk egg with remaining sugar until just combined. Paint mixture onto top shell, taking care to avoid the outer edge.
Bake 15 minutes at 425; then reduce oven temperature to 375 and bake 25 to 35 minutes longer.
The pie is ready when the filling has been boiling for at least 5 minutes.

OPTIONAL ADD-ONS
Dust the top crust with a sprinkling of large sugar granules before baking. Or forgo the second shell altogether and opt for a cobbler-style nut-crumb topping instead.
