Old-Fashioned Strawberry Shortcake

(from myrecipes.com)

3 1/2  cups  halved strawberries, divided
1/3  cup  sugar
1/3  cup  orange juice
2  teaspoons  vanilla extract
1  teaspoon  lemon juice
1 1/4  cups  all-purpose flour
3  tablespoons  sugar
1  teaspoon  baking powder
1/4  teaspoon  baking soda
1/8  teaspoon  salt
3  tablespoons  chilled stick margarine or butter, cut into small pieces
1/2  cup  low-fat buttermilk
Cooking spray
6  tablespoons  frozen reduced-calorie whipped topping, thawed
Whole strawberries (optional)

Combine 1 cup strawberry halves, 1/3 cup sugar, orange juice, vanilla, and lemon juice in a bowl, and mash with a potato masher. Stir in 2 1/2 cups strawberry halves. Cover and chill.

Preheat oven to 425°.

Lightly spoon flour into dry measuring cups; level with a knife. Combine flour, 3 tablespoons sugar, baking powder, baking soda, and salt in a bowl; cut in margarine with a pastry blender or 2 knives until mixture resembles coarse meal. Add buttermilk, stirring just until moist (dough will be sticky).

Turn dough out onto a lightly floured surface, and knead lightly 4 times with floured hands. Pat dough into a 6 x 4-inch rectangle. Cut dough into 6 squares. Place 1 inch apart on a baking sheet coated with cooking spray. Bake at 425° for 12 minutes. Cool on a wire rack.

Split shortcakes in half horizontally using a serrated knife; place each bottom half on a dessert plate. Spoon 1/4 cup strawberry mixture over each bottom half. Top with shortcake tops; spoon 1/4 cup strawberry mixture over each top. Top each serving with 1 tablespoon whipped topping; garnish with whole strawberries, if desired.
