How to Make It
To prepare crust, lightly spoon flour into a dry measuring cup; level with a knife. Place flour, 2 tablespoons sugar, cream cheese, butter, and salt in a food processor; pulse 5 times or until mixture resembles coarse meal. With processor on, add ice water through food chute, processing just until combined (do not form a ball). Press the mixture gently into a 3-inch circle on heavy-duty plastic wrap; cover with additional plastic wrap. Chill for 15 minutes.
Preheat oven to 400°.
Divide dough into 4 equal portions; place each portion between 2 sheets of plastic wrap. Roll each portion into a 5-inch circle. Place dough in freezer for 5 minutes or until the plastic wrap can be easily removed.
To prepare filling, combine blueberries and next 4 ingredients (blueberries through juice) in a bowl. Working with 1 dough portion at a time, remove plastic wrap from dough. Place dough on a lightly floured surface, and brush with egg white. Spoon about 2 tablespoons blueberry filling onto half of circle. Fold dough over filling, and press the edges together with a fork to seal. Place the turnover on a foil-lined baking sheet coated with cooking spray. Lightly coat turnover with cooking spray, and sprinkle with 1/4 teaspoon sugar. Pierce the turnover with a fork. Repeat procedure with remaining dough, egg white, filling, and sugar.
Bake at 400° for 15 minutes or until lightly browned. Remove from pan, and cool on a wire rack.
Note: Expect the blueberries to ooze out of the crust a little during baking.
