Tips
Make the pistachio crunch up to 2 days ahead and store in airtight container to save time on baking day.
Use room temperature cream cheese for smoothest filling - leave out 2-3 hours or microwave briefly to soften.
Run a knife around edges after cooling to prevent cracks, and chill overnight for cleanest slices.

FAQ
Can I make this without a springform pan?
Yes, use a 9-inch round cake pan lined with parchment, but removing cleanly will be more challenging. Consider making individual portions in ramekins instead.
What if my caramel crystallizes while cooking?
Start over - once crystallized, caramel cannot be saved. Cook without stirring once boiling begins, and ensure your pan and utensils are completely clean.
How long will this cheesecake keep in the refrigerator?
Properly covered, it will stay fresh for up to 5 days. The texture actually improves after the first day as flavors meld together.
