I boiled half a pot of water n put them in (like making "buah Melaka") and waited for it to rise up and scooped them out, and rolled them around in tapioca powder+fine sugar mix. Oh, I did add some fine sugar with the glutinous rice flour, just to give a little hint of sweetness.
But I'll try harder next time. Mochi-making is really not as easy as we all think! We need the right ingredients to make it. Please don't follow this weird recipe. This is just to share my awkwardness in the kitchen. Should any Japanese chef read this, please DO tell me how to make mochi the right way!
