Tips
Ensure cream cheese is fully softened before mixing to prevent lumps in the cheesecake filling. Room temperature ingredients blend more smoothly.
Cool the cheesecake gradually in the oven to prevent surface cracking. The slow temperature change helps maintain a smooth top.
Whisk custard constantly while cooking to prevent curdling. Remove from heat as soon as it coats the spoon to avoid overcooking.
Good to Know
Refrigerate covered for up to 5 days. Best texture when served within 3 days.
Can be made 1-2 days ahead. Add ganache day of serving for best appearance.
Serve chilled. Use sharp knife dipped in warm water between cuts for clean slices.
Common Mistakes
