First Step: Prepare baking environment and crust basePreheat the oven to 350°F (175°C). Mix 1 cup chopped pistachios and 1 cup walnuts with optional ground cinnamon and cardamom. Lightly grease a 9-inch springform pan and unroll thawed phyllo dough. Begin layering phyllo sheets, brushing each generously with melted butter. After stacking five sheets, evenly sprinkle a generous ½ cup of the nut mixture. Repeat layers of phyllo and nuts until all ingredients are used, finishing with five layers of buttered phyllo on top. Press the dough firmly and score the top layer in a diamond pattern without cutting all the way through to separate slices.

Second Step: Bake the crustBake the phyllo and nut crust for approximately 15 minutes or until golden and crisp. Remove from oven.

Third Step: Prepare the honey lemon syrupWhile the crust bakes, combine ¼ cup honey, ¼ cup water, lemon juice and zest, and vanilla extract in a saucepan. Bring to a boil, then reduce heat and simmer for 9 to 10 minutes until slightly thickened. Reserve 1 tablespoon syrup for topping later.

Fourth Step: Apply syrup to baked crustPour the remaining syrup evenly over the hot baked crust. Let it absorb and cool for 10 minutes. Mix the reserved nuts (¼ cup pistachios and walnuts) with the reserved syrup to create a honey-glazed nut topping for garnish.

Fifth Step: Prepare water bathPreheat 4 cups of water to boiling to prepare a water bath for baking the cheesecake, which ensures gentle and even cooking.

Sixth Step: Make cheesecake fillingIn a large mixing bowl, beat cream cheese, honey, lemon zest, and kosher salt until smooth and creamy. Add eggs one by one, blending well after each addition. Stir in vanilla extract and cornstarch at low speed until fully incorporated. Optionally, for a richer texture, fold in 1 cup sour cream or labneh. Strain the filling through a sieve for extra smoothness if desired.

Seventh Step: Assemble and bake cheesecakePour the cheesecake filling over the syrup-soaked crust. Gently tap the pan on a counter to remove air bubbles. Wrap the springform pan tightly in foil to prevent water leakage, then place it in a larger baking dish. Pour boiling water into the larger dish to create a steam bath. Bake at 350°F (175°C) for 1 hour until the cheesecake is set but with a slight jiggle in the center.

Eighth Step: Cool and garnishTurn off the oven and slightly slide the cheesecake out of the oven. Evenly sprinkle the honey-glazed nut topping on the cheesecake. Return the oven door ajar and let cool for 1 hour gradually.

Final Step: Chill and serve Remove from oven, discard foil, and cool on the counter for 45 to 60 minutes. Refrigerate for at least 6 hours or overnight before slicing. Serve chilled with optional fresh honey drizzle or extra nuts. Vegan or gluten-free adaptations may require slight adjustments in baking time.
