Strawberry Shortcake

I love to go strawberry picking and today we brought home over 5 pounds! I have a feeling as I find ways to use the strawberries we picked this evening, I'll find a few more things to post on here as well.
This recipe is for 12 shortcakes. I cut it in half for us and just used 1 egg white.

3 cups all-purpose flour
1/4 cup white sugar
4 teaspoons baking powder
3/4 teaspoon cream of tartar
1 cup butter
2/3 cup heavy cream
1 egg, beaten
3 cups sliced fresh strawberries
3 tablespoons white sugar Preheat oven to 350 degrees F.

In a large bowl, mix flour, 1/4 cup sugar, baking powder and cream of tartar. Cut in butter with pastry blender or two knives. Stir in cream and egg. Turn out onto a lightly floured surface and knead 2 minutes. Press into a half-inch thick sheet. Cut into squares. Place on baking sheets.
Bake in preheated oven 20 minutes, or until golden. Sprinkle 3 tablespoons sugar over sliced berries.
Let shortcakes cool before splitting and filling with sugared berries.
