I want to make a variety cheesecake, like the ones sold the stores. I've found a double cake and a checkerboard batter separators online. What I'm looking for is a batter separator that is made of metal or other material that can be left in during baking and is in the shape of slices. My goal is to make a cheesecake with 3-4 diffrent flavors. Does this exsist?? Thanks!
