Properly made tapioca pudding has a different texture than the garbage you can buy premade. It does not have the same texture as jello and jello can have a different texture based on the amount of water you use to make it. I haven't had flan or bubble tea, I will bow to your wisdom about those.Sorry, it is a textural thing for meI don’t like tapioca, jello, flan, bubble tea...you get the picture.
