This recipe shows you how to make a rich and dense New York cheesecake. A base of crushed biscuits is used, and then cream cheese (at room temperature), sour cream, and granulated sugar are carefully mixed together. Eggs, lemon juice, and heavy cream are then added to create a smooth batter, which is then poured into a mold. After baking slowly in a water bath, it is chilled in the refrigerator for a day to create a moist, melt-in-your-mouth cheesecake. Sprinkle with powdered sugar if desired, and it's perfect for a home café or for entertaining guests.
