By the look if this picture, most of us in Kota Kinabalu know what is this.
In Chinese, we called it 'Ngao sin tart'. Yes, the word 'tart' is English actually.
Now let's talk about the taste of this.
The yellow is the custard and this white foamy thing around it is the sugar. Both of this stand on the little piece of butter cake. Simple at it is; it's sweet and delicious. Originated from another part of Sabah, Sandakan.
