Homemade Taiwanese pudding. 
To make a vegan dessert, just add hot water!
Put 700ml (about 3 bowls) hot water (above 90 degrees) into a large container.  Add the whole box of pudding  powder and stir until completely dissolved.  Pour into  small containers and let them cool down.  The taste is especially good after refrigerating.  Store in the refrigerator with lids (to avoid bad ordors) for up to 7 days. The amount of water can be increased /decreased by 50mL to adjust the hardness.
