Quoted from mothership, this cake actually originates from the Kantin stall in Kuching, Sarawak, Malaysia. The sponge itself is made from soft lemon butter cake, adorned with English orange jam that provides a refreshing taste. On top of it, there is an addition of lemon foam to create a more realistic sponge illusion. To enhance its realistic impression, this dish is served in a detergent bottle, complete with pandan syrup and lime juice for added interesting flavor.

Apparently, this cake has become a trend on Chinese social media, especially on April Fools' Day. A visitor even shared their funny experience when trying this dish. Initially, they felt teased by the waiter with the dish, but they were surprised by the freshness and deliciousness of the cake.
