One of the things which Japan modified for its tastes was flan, or, if you prefer, pudding, or, even "creme brulee" without the burnt top. I've always been confused about whether this should be called one or the other. As you can see by the side view, this is essentially flan. It has a sweet syrup on the bottom and a thick pudding in the center. Personally, the point at which flan and pudding are separated comes at how thick they are. Flan can stand on its own, though it may wobble a bit. Pudding tends to be a bit more gooey and needs a container to support it. At any rate, the plastic containers of "purin" that you see here were in a supermarket in Tokyo and they have whipped cream as well as chestnut puree (the ones on the right). The ones on the left are "fruit purin", but the curious thing about them is that they have a mini purin on top of the larger purin. It feels like one of those mirror within a mirror deals, only with food.
