For an extra smooth cheesecake, ensure your cream cheese and eggs are at room temperature before mixing. If you don't have a 7-inch springform pan, you can use an 8-inch pan, but reduce the cooking time by 5 minutes. To prevent condensation from dripping onto the cheesecake during cooling, you can place a paper towel under the plastic wrap. For a richer flavor, try using brown sugar instead of white sugar in the sour cream topping. Garnish with fresh berries or a drizzle of chocolate sauce before serving for an elegant presentation.
