In the past, when I was in university.
I went to the San Xia Old Street and Shenkeng Old Street.
I saw a lot of people selling colored cake on the street.
That's the cool cake. Today we are going to make Taiwan cool cake.
The cool cakes are generally red, yellow and orange.
Today, I made blue color with the butterfly pea flower.
Ingredients:
Sweet potato flour 50g
Water 150g
Rock sugar 25g
dried butterfly pea flower 2T
Proper amount of oil
