Kuih Keria is one of many delicious traditional Malay kuihs. It is made of sweet potato and flour and coated with crystalised/caramalised sugar. I have tried making them myself before using the sweet potato/yam that was sold at the regular supermarket i.e. Ralph's, Von and etc. The result was rather a disaster. They were too watery and I had to add a lot of flour to be able to make a dough out of them. That only resulted in a hard Kuih Keria. Not the typical soft and slightly chewy delicious Kuih Keria but a rock hard one! That was maybe 3 years ago. I haven't even bothered making them again until recently when I was told to use Japanese yam that is sold at the asian supermarket. Some of my friends in other states told me that it's called Korean yam. I guess the name varies depending on where you buy them or who sell them. Japanese or Korean yam, as long as they give me a delicious Kuih Keria, I am happy.
