Cut Crisco into flour. Mix together liquids and salt and blend into flour mixture. Knead well. Roll out on floured surface and cut into 6 squares, approximately 6 inches square.

Adjust oven rack to lower-middle position and heat oven to 425 degrees.

Mix butter, brown sugar, cinnamon and nuts in a small bowl. Spoon a portion of the mixture into each hollowed out apple.

Set an apple on each square of dough. Bring up the four corners of dough around the apple and pinch edges to seal. Place on a large greased baking dish or cookie sheet.

Brush dumpling tops and sides with egg white; sprinkle with sugar.

Bake dumplings until pastry starts to turn golden brown, around 10 minutes. Reduce heat to 375 F. and bake until golden brown, around 20-30 minutes longer.

Bring water, butter, brown sugar and cinnamon to a boil in a small saucepan. Add cornstarch/water mixture. Whisk into hot syrup for a smooth sauce. Cover, and keep warm.

For each serving, spoon a portion of sauce on a dessert plate. Set apple dumpling over warm sauce; serve immediately.
