What are some reasons Royal® Tapioca Pudding may fail to thicken?
— When milk substitutes are used. The calcium in milk is essential for the setting process. — When pudding is not cooked properly. It should be cooked over medium heat, stirring steadily until it comes to a complete boil with bubbles breaking all over the surface. The mixture will be thin but will thicken as it cools. — Pudding should cool slightly, then refrigerate at least ½ hour. For firmer set, refrigerate for 1 hour. Stir before serving to distribute the tapioca granules.
