i have tried the traditional yam paste with pumpkin sauce, its no good! its yellow in colour, look like oil. dunno how to describe, its just not nice. if you realli want yam paste, i will reckon not to do the pumpkin sauce.
think sweetened taro cream is 'not nice' because according to Sheena, those who do not know what it is will think that it is a watery yam paste.
anyway have changed to mango heart shape pudding. tot its quite interesting.
