I saw a food blogger post this on Instagram and told my boyfriend that we should go and try it. He arrived that same day at my place with it!! Hehehe im a lucky girl. The liu sha filling was perfect, the right balance of salty and sweet. The bun was nice and crispy after reheating, and it had a pretty purple exterior. You can't really taste any hint of sweet potato though, but that's alright for me cos it was enjoyable nonetheless! I could have three of these in one go!
