Marlene Sorosky’s Lemon Mousse Cheesecake: A Zesty Dream

My grandmother, a woman whose culinary skills were as comforting as her hugs, had a small, worn cookbook filled with family favorites. Tucked within its pages, stained with memories of countless celebrations, was a clipping for a Lemon Mousse Cheesecake. Although she usually stuck to her repertoire of apple pies and chocolate chip cookies, I remember her experimenting with this recipe one summer. The light, tangy aroma of lemon filled her kitchen, a welcome change from the usual smells of cinnamon and vanilla. It was a revelation – a dessert that was both elegant and utterly delicious. This recipe always brings me back to those summer days in my grandmother’s kitchen.

Instructions

Prepare the Crust: Begin by buttering a 10- x 2-inch springform pan with 1 tablespoon of butter. This prevents the crust from sticking and ensures easy removal. Next, seal the outside of the pan with foil. This is crucial for preventing water from seeping in during the water bath.
Crush the Wafers: Place the vanilla wafers and 1/4 cup sugar in the workbowl of a food processor. Process until you achieve fine crumbs. If you don’t have a food processor, you can achieve a similar result by placing the wafers between two sheets of waxed paper and crushing them with a rolling pin.
Combine and Press the Crust: Melt the remaining 4 tablespoons of butter and process (or mix) it into the wafer crumbs. Press the crumb mixture evenly over the bottom of the prepared springform pan. Ensure the crust is compact for a firm base.
Prepare the Lemon Zest and Juice: Grate 1 tablespoon of lemon zest from the lemons and set it aside. Then, squeeze the lemons to obtain 3/4 cup of lemon juice and set it aside separately. Having these prepped makes assembling the filling much smoother.
Whip the Egg Whites: Separate the eggs. In a clean bowl, whip the egg whites to soft peaks. Gradually add 1/4 cup of sugar while continuing to whip until you achieve firm, glossy peaks. Set the whipped egg whites aside. These will lighten the cheesecake and provide a mousse-like texture.
Beat the Cream Cheese: In another bowl (no need to wash the beaters from the egg whites), put the softened cream cheese and beat until completely smooth. Gradually add 1 1/4 cups of sugar and beat until the mixture is light and fluffy, about 5 minutes. This step is crucial for achieving a smooth and creamy cheesecake filling.
Combine the Filling Ingredients: Add the flour, egg yolks, lemon juice, and lemon zest to the cream cheese mixture. Beat until smooth, approximately 1 minute. Ensure all ingredients are well incorporated.
Fold in the Egg Whites: Gently fold the whipped egg whites thoroughly into the lemon batter. Be careful not to overmix, as this will deflate the egg whites and result in a denser cheesecake.
Prepare the Water Bath: Adjust the oven rack to the middle position and preheat the oven to 325 degrees F (160 degrees C). Pour the batter into the prepared springform pan. Place the springform pan in a baking dish just large enough to contain it. Then, place the dish in the oven and add hot tap water to the baking dish, ensuring it comes about 1 inch up the side of the springform pan. The water bath creates a moist environment that prevents the cheesecake from cracking and ensures even cooking.
Bake the Cheesecake: Bake the cheesecake until it is set and golden, approximately 55 to 65 minutes. The center may still jiggle slightly, but it will set further as it cools. To test for doneness, gently shake the pan; the edges should be set, and the center should have a slight wobble.
Cool and Chill: Transfer the pan to a wire rack to cool completely. Once cooled, cover the cake and refrigerate it until thoroughly chilled, at least 4 hours. For optimal flavor and texture, chilling overnight is recommended. The cheesecake can be refrigerated for up to 3 days or frozen for up to one month.
Serve: To serve, heat a knife with hot water and wipe it dry before each slice. This will ensure clean, smooth slices. Run the knife along the edge of the cake to loosen it from the pan. Carefully remove the pan rim. Slice the cake, heating and wiping the knife clean each time. Garnish slices of cake with Candied Lemon Zest (optional).
Prepare the Candied Lemon Zest (Optional): Using a floating blade vegetable peeler, carefully peel the zest from 1 lemon. Trim the zest into narrow strips about 2 inches long. Put the zest in a small nonreactive saucepan with water to cover, and boil for 5 minutes. Drain and rinse with cold water. This blanching process removes bitterness from the zest.
Make the Syrup: Bring 1 cup sugar, 1/3 cup light corn syrup, and 1/3 cup water to a boil in the saucepan. Remove from heat, stir in the blanched zest, and let stand for 30 minutes. Bring the liquid back to a boil and let stand for another 30 minutes. The soaking process allows the lemon zest to absorb the sweet syrup.
Dry and Sugar the Zest: Using a fork, remove the zest strips from the syrup and transfer them to a wire rack set over a pan to catch the drippings. Discard the syrup. Put 1/2 cup sugar on a plate. Roll the zest strips in the sugar until they are fully coated.
Store the Candied Zest: The Candied Lemon Zest can be stored at room temperature for up to 1 week. This adds a beautiful and flavorful garnish to the cheesecake.

Expert Tips & Tricks

Preventing Cracks: To minimize the risk of cracking, avoid opening the oven door during baking. The water bath also helps maintain a consistent temperature and moisture level.
Cream Cheese Temperature: Ensure your cream cheese is fully softened before beating it. This will prevent lumps and create a smoother filling.
Flavor Boost: Consider adding a teaspoon of vanilla extract to the cream cheese mixture for an extra layer of flavor.
Freezing: To freeze the cheesecake, wrap it tightly in plastic wrap and then in foil. Thaw it in the refrigerator overnight before serving. Slicing a partially frozen cheesecake results in neater slices.
Lemon Intensity: Adjust the amount of lemon zest and juice to your preference. For a more intense lemon flavor, add the zest of 2 lemons.

Serving & Storage Suggestions

This Lemon Mousse Cheesecake is best served chilled, allowing the flavors to meld and the texture to firm up. Garnish each slice with Candied Lemon Zest, a sprig of fresh mint, or a dollop of whipped cream. It pairs beautifully with a glass of chilled Prosecco or a cup of herbal tea.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze individual slices wrapped tightly in plastic wrap. When ready to enjoy, thaw the slices in the refrigerator for several hours.

Variations & Substitutions

Gluten-Free Crust: Substitute the vanilla wafers with gluten-free graham crackers or almond flour for a gluten-free crust option.
Dairy-Free Option: While challenging to replicate perfectly, you can experiment with using plant-based cream cheese alternatives and a vegan butter substitute for the crust. The flavor and texture will differ, but it can still be a delicious alternative.
Berry Swirl: Before baking, swirl in a berry compote (such as raspberry or blueberry) into the cheesecake batter for a burst of fruity flavor and visual appeal.
Lime Mousse Cheesecake: Replace the lemons with limes for a tangy twist.
Chocolate Crust: Substitute some of the vanilla wafers with chocolate wafers for a decadent chocolate-lemon combination.

FAQs (Frequently Asked Questions)

Q: Why do I need a water bath for this cheesecake?
A: The water bath provides a gentle, consistent heat that prevents the cheesecake from cracking and ensures a creamy, even texture. It also helps to regulate the baking temperature, preventing the edges from overcooking before the center is set.

Q: Can I use store-bought graham cracker crust instead of making my own wafer crust?
A: Yes, you can use a store-bought graham cracker crust, but be sure it is a deep-dish version to accommodate the filling. However, the homemade vanilla wafer crust complements the lemon flavor exceptionally well.

Q: How do I know when the cheesecake is done?
A: The cheesecake is done when the edges are set and the center jiggles slightly when the pan is gently shaken. It will continue to set as it cools. Avoid overbaking, as this can result in a dry or cracked cheesecake.

Q: Can I make this cheesecake ahead of time?
A: Absolutely! This cheesecake is ideal for making ahead of time, as it needs several hours to chill. You can make it a day or two in advance and store it in the refrigerator until ready to serve.

Q: Is it possible to freeze the cheesecake?
A: Yes, the Lemon Mousse Cheesecake freezes well. Wrap it tightly in plastic wrap and then in foil to prevent freezer burn. Thaw it in the refrigerator overnight before serving.
