FOR THE PIE FILLING
Cut enough berries in half to equal 2 cups. Process in a food processor or blender until very smooth. You should have 1-¼ cups of puree.
In a medium saucepan, combine puree, 1-cup sugar, 1-tablespoon pectin, and pinch of salt. Bring to boil and boil for one minute. Take off the heat, and skim any foam that may have formed on top.
Mix the 3 tablespoons cornstarch with ¼ cup cold water until smooth. Add to strawberry mixture and return to boil. Lower heat and simmer for a couple of minutes until mixture becomes pretty clear. It will be very thick. Remove from heat and cool to room temperature.
Reserve ¼ cup of mixture and set aside.
Slice 1 quart of remaining strawberries into halves or quarters – whatever you prefer.
Fold the sliced berries into the glaze mixture. Go slowly and make sure all the berries are evenly coated with glaze. Refrigerate until cold.
Right before serving: Turn the glazed strawberries into the tart shells, if using. Spread fruit evenly.
FOR THE SHORTBREAD COOKIE CRUST – TWO OPTIONS
Preheat oven to 350 degrees.
Process cookie crumbs in food processor until finely ground
Add sugar and melted butter and process until mixed well
Option 1: Press onto bottom and sides of tart pans. Bake for 10 minutes. It will feel soft, but will firm up as it cools.
Cool completely before filling.
Option 2: Spread the crumb mixture out on a cookie sheet and press down. Bake for about 10 minutes. Allow to cool and break into pieces or crumble between your fingers to make crumbs. This plan works well if you are going to make individual servings in small Mason jars: Line the bottom of the jar with crumbs as deep as you want, spoon on the cold filling, and top with whipped cream or ice cream
