1. With whisk, blend sugar and flour in a large sauce pan. Add milk gradually, whisking to combine. Cook on medium heat, whisking constantly, to boiling. Boil one minute, stirring. Remove from heat. Whisk egg yolks thoroughly in a small bowl, then pour some of the hot milk mixture in and combine. Return milk mixture to the stove, and add egg mixture, whisking constantly.
