New York Cheesecake

Thought of doing a cheesecake to use up the sour cream before it expires, try this recipe as its quite small portion compare to other cheesecake recipes, this portion is just nice for my family. Although this is a rich cake but all like it. Recipe from 孟老师的下午茶...

(I use a 7" cake ring althought the book recommended 6" springform pan)
