2 cups white sugar
4 teaspoons ground cinnamon
4 cups chopped pecans
2 egg yolks
1/2 teaspoon vanilla extract
1/3 cup warm water
1 (9 inch) prepared graham cracker crust
In a medium saucepan over medium heat, combine sugar, cinnamon and pecans. Cook, stirring frequently, until mixture comes to a boil. Immediately remove from heat and stir in egg yolks and vanilla, water and cinnamon. Stir in 8 cups of flour. Stir in biscuit mixture, 1/2 cup at a time, until dough is up to the size of lumps in a small bowl.
Divide dough into eight pieces, wrap each piece into a waxed paper and cut into 4-inch circles. Place on prepared crust. Chill in refrigerator for at least 2 hours, or overnight.
