Flaky Kringle (Excellent)

Grandma thought this recipe was most excellent, as the title indicates.  I remember having this as a kid and it was delicious, but it always seemed kind of difficult to make.

Ingredients:

• 2 Sticks Butter
• 2 Cups Flour
• 1 Cup Sour Cream
• 2 Egg Whites, Beaten
• 2 Cans Pie Filling (Cherry or Apple)

Directions:

• Mix together butter, flour, and sour cream to form a dough.
• Knead until well combined.
• Separate into four pieces and roll into balls.
• Wrap each ball in wax paper and refrigerate overnight.
• Preheat oven to 350.
• Roll out one ball of dough onto floured board until it is 8" x 16" in size.
• Brush dough with melted butter and then beaten egg whites.
• Spread pie filling in center of dough, sparingly.
• Fold both sides to center and roll ends to hold in filling.
• Brush top of dough with beaten egg whites.
• Bake at 350 for 35 minutes or until golden.
• Makes four kringles (you best have a lot of company coming over).
