I went to learn the way to make a medical cake. I'm interested in healthy foods and eastern medicines. We did not use suger at all for the cake. We used xylitol instead of the suger. I've heard that it is good for our health and low calory, what's more it prevents from a sudden rise of a blood-suger level. I will use it for the ingredients of cakes from now! I have to search where I can buy it. We used powdered green tea as well. It was good for our health too. The cake was very delicious!! ^^
