I am of Polish ancestry (both parents were Polish) and this is the recipe I came across recently that seems to be like the cheesecake we had at Easter when I was a child. This uses farmer's cheese or cottage cheese and Splenda. You can use regular sugar as well. The following note is what drew me to this recipe, because the cheesecake I had as a child was very dense and heavy: "NOTE: I found this filling to be heavy and dry, which surprised me as I assumed all the whipped ingredients would lighten it. I was wrong."
