In a small bowl, whisk the cornstarch and water together, until no clumps remain. 2-Whisk in the potato starch mixture into the saucepan and place it over medium heat. Stir it regularly, until it begins to simmer. Reduce it to low, and continue to mix for a further 5-6 minutes, until it has thickened. Remove the saucepan from the heat. Let the pudding mixture cool to room temperature, before refrigerating it for at least an hour, until chilled.
