I use lemon zest instead of lemon or lime juice in my cheesecake. I make a NY Style cheesecake (cooking-wise, IIRC NY Cheesecake doesn't usually incorporate the lemon) and a no sugar added blend of artificial sweeteners. I also make an almond meal crust as I have a nasty reaction to gluten and wheat.
This Blueberry topped cheesecake won the coveted (ahem, right...) Golden Spatula Award at the office.
