Step 1: Prepare the filling
Step 2: Filling the pie shell
Place the circle of dough into the pan, pressing it in place and then trim any excess from the edges of the pan. I use a deep, ceramic pie plate because I like lots of filling and the ceramic keeps the crust from getting soggy. Add the filling to the dish, alternating between sections of strawberries and sections of blueberries.
* There are lots of recipes and instructions for pie dough. I like this one:
Sift together two cups of flour, a teaspoon of salt and a tablespoon of sugar. Add, in small pieces, a 1/3 cup of butter (for great taste) and 1/3 cup of shortening (for great texture). Use a pastry cutter to mix the fat and the flour together until all the lumps are pea-sized. Add up to 1/3 cup of cold water, a teaspoon at a time, gently squeezing the mixture (never kneading!) until it holds together in a ball. Chill for half an hour.
Step 3: Decorating the top of the pie
Use the remaining scraps of dough to make five little stars. To make a star, first cut a pentagon, then cut out a little notch from each side of the pentagon. They don't have to be perfect -- they look fine if they're a little crooked.
As a final flourish, take a fork and use the tines to mash down the edge of the pie crust all around the edge of the dish.
