Key Lime Cheesecake

READY IN: 1hr 38mins
Recipe by Juenessa

What makes this recipe so exceptional is the lime custard on the bottom, which makes it seem like you're not only eating cheesecake but key lime pie, too. **This cheesecake needs to be refrigerated overnight.**

This was an awesome cheesecake! I didn't use the crust recipe, but used another I found on recipezaar that was an Alton Brown recipe for macadamia nut crust. I made it for a belated housewarming party, and it got rave reviews from everyone who attended. The only improvements I would make would be to make the cheesecake and and lime curd layers thicker, since they were so delicious! My thanks for a delicious and easy to follow recipe!
