When ready to serve, pour the coconut custard over the jelly. Either crumble cookies on top of the custard, or serve the cookies alongside the dessert.
If you don’t want to use jasmine tea, you can omit and use plain water instead of tea, or you can substitute for another kind of tea.
If you don’t want to serve this with cookies, you can top with toasted almonds, roasted sesame seeds, or crushed black sesame candy.
