Lithuanian Semi-Crisp Meringue Pastry

This is from the "Art of Lithuanian Cooking". I haven't made it yet; times are guesstimates.

Directions

1. Mix together flour, butter, sugar, vanilla, egg yolk, sour cream and baking powder. Work until smooth. Place in fridge for 30 minutes.
2. Meanwhile, preheat oven to 350 degrees.
3. Roll out dough and placed on a small, greased cookie sheet. Pierce with a fork in several places before putting it into the oven. Bake at 350 for 25 - 30 minutes or until lightly golden. Remove and cool slightly.

5. Spread the marmalade over the top of the pastry.
