Sweet Potatoes with Black Sesame Chiffon

Small pieces of sweet potatoes housed in the pocket.

This is not something new on my blog. It's the purple sweet potato chiffon I have made before. This time round I just added some small pieces of Japanese sweet potatoes and black sesame seeds to make it more JAPANESE! However the taste is the same. I was hopping the colour of the cake might turn out to be more purple. But it didn't.
