The inspiration of making this mochi cake came from a Korean mom that I talked to. I never thought of adding sweet potato into a mochi cake until I tasted some that she made. Hers was different with orange sweet potato and some other things that she added (she didn't give me the recipe though). Since I LOVE the purple sweet potato because of the color and sweetness, I wanted to recreate her recipe and hence this recipe was born. I was glad to say that it was a success and we all loved it very much. On the day it was baked, the crust was crusty and the mochi was chewy with the sweetness from the sweet potato and a little sourness from the raisins, just perfect! The crust will turn soft on the 2nd day but just as chewy and delicious! This is definitely my keeper recipe that I want to make all the times. Next time I want to try it with taro and play with this recipe a little. Feedback to me if you ever try it!
Seriously it was so hard to stop at just one piece, got to have two!! Self-control....self-control....
