The cheesecake mixture is not 滑 and with 粒粒. Those 粒粒 is jelly. I stir up the jelly powder with gelatine at very beginning (then it is 凝固 under such cold weather). Then, when mix jelly water into cheese and cream, it cannot dissolve and became 粒粒.
Then, next time, I think I have to put the jelly water into hot water before use to prevent them 凝固. Am I right?
