Starlight Crisps

This is a recipe from my mom. I am not sure who found it, but I believe it was my Grandmother McElwain.

Starlight Crisps:

Soften one package of yeast (2 ¼ tsp) in 1/4 cup very warm water.

Mix together 3 3/4 cups flour and 1/2 tsp salt in bowl.

Cut in 1 cup butter until particles are the size of peas. (I use the food processor)

Blend in 2 eggs, 1/2 cup sour cream, 1 tsp vanilla, and the yeast.  Mix thoroughly.  Cover; chill at least 2 hours.

Combine 1 1/2 cups sugar with 2 tsp vanilla

Roll out half of chilled dough on counter which has been sprinkled with about 1/2 cup of vanilla sugar.  Roll out to a 16 x 8 rectangle.  Sprinkle with about 2TB more vanilla sugar.  Fold one end of dough over center.  Fold other end over to make three layers.  Turn 1/4 way around and repeat rolling and folding twice, sprinkling board and dough with additional vanilla sugar as needed.  Roll out finally to 16 x 8 rectangle again about 1/4 inch thick.  Cut into 4 x 1 inch strips.  Twist each strip 2 or three times.  Place on greased cookie sheet. Put in fridge for 10 minutes. 
Bake at 375 degrees for about 15-20 minutes until light golden brown.  (DO NOT UNDERBAKE or it will be doughy).  Repeat with remaining chilled dough.
