Am trying to experiment w/baking my first cheesecakes! From a 40-year old recipe in my files, I baked my fourth, and I think it is delicious. However, I suspect the baking time is off...it said to bake @475º - 10 minutes; 200º - one hour; oven off for one hour. After it cooled on the counter, I transferred to a platter, where it proceeded to run all over my kitchen counter. So I had, actually, cheesecake soup. I am thinking, perhaps, at that low degree of 200, I should bake 2-3 hours? Help, please. Thank you.
