Posting this for safekeeping, since it combines two of my favorite things -- cheesecake and guava. Adapted from "In the Sweet Kitchen" by Regan Daley. NOTES: 1. Fresh guavas are recommended for the filling, but I'm sure that canned ones would work just fine if, like me, you can't get your hands on a decent fresh guava in your area. 2. Allow at least two days to make this, because both the unbaked crust and the finished cheesecake need chilling time, preferably overnight. The unglazed cheesecake can be made up to 3 days ahead. Cook time includes chilling times.
