If you grew up in Hong Kong, you’d find 肚臍餅 (belly button biscuits, how’s that for alliteration?) a familiar sight. It was one of my favourite biscuits to eat as a kid. Mind you, I’d just eat the sugary top and leave the biscuit but I think that’s true for every kid. It was a nice nostalgic moment when I walked into Causeway Bay’s GOD and found a plate of these biscuits lying around. Thing was, the biscuits smelt much better than I recall with this delicious vanilla scent coming from them. Then I realised that they were clay aroma diffusers! What an ingenious idea for bringing a childhood memory back to life.
