A slower bake, in a bain marie (water bath,) and a long slow cool in the oven. Ideally, turn the heat off before it's set (165 F or so,) crack the over door to bleed off most of the heat, and let it sit for half an hour to an hour. I want to get to a point to where the egg proteins just bind it together, and are fully pasteurized. Unfortunately, this does take a couple of hours in the oven in total. I don't see this working for you if you're baking more than a couple. My desire to get to a crackless cheesecake is my predeliction. Cracked cheesecakes are still awfully good.We’ve discussed this for many years and decided that cheesecakes without crack are just cheesefakes.
I’d be curious to hear how you stop the cracking. We experimented with a few different techniques, all which failed. So we chalked the cracks up to personality. Each cakes has their own personality.
