For Freezing: Cheesecake can be frozen up to 3 months without the topping.
Non-US Ingredients: You can replace graham crackers with 240g of ground digestive biscuits. Use golden syrup as an alternative to corn syrup if needed.
Water Bath: A traditional water bath can also be used as mentioned in the original recipe. But ensure to wrap the springform pan with aluminum foil to prevent leaks.
