Finally got my hands on this after years

On top of their ulu location, to get a slice you have to call in advance at 1030am on the day itself to check for availability. There was literally just one slice that day lol, but otherwise their sunshine(mango yuzu meringue) should make for a good substitute

This cake is really really light, it's no trouble finishing this huge slice at all. The exterior is perfect, it's properly dehydrated and very airy with a good crunch, and the interior is chewy. I'm no baker but I presume it takes great skill to achieve a balanced texture like this. Further, the passsionfruit taste in the cream comes through nicely and works brilliantly

Worth a try for sure, though idk if it's worth the trouble
