Mix sugar and lemon zest in a bowl until it smells fresh and citrusy. Add the flour and baking powder. Stir in the egg and cooled browned butter.
Mix everything until a soft dough forms. Press it evenly into the bottom of your cheesecake pan. Make sure there are no gaps.
Preheat the oven to 350°F (175°C).
Bake the crust for 10 minutes until lightly golden. Set it aside to cool a little while you make the filling.
In a small bowl, stir the cornstarch and heavy cream until smooth.
In another bowl, mix the Greek yogurt and condensed milk until combined.
In a large bowl, beat the cream cheese, sugar, and eggs for 5 to 10 minutes until fluffy and light.
Slowly add the yogurt mixture and the cornstarch blend. Stir gently until the batter is smooth.
Pour the batter over the cooled crust. Shake the pan lightly to even out the top.
Bake at 350°F (175°C) for 1 hour. Turn off the oven, leave the cake inside with the door closed for 10 minutes to help prevent cracks.
Take the cheesecake out of the oven and let it cool to room temperature. Then chill in the fridge for 4 to 6 hours or overnight until it’s fully set.
Spread strawberry jam on top of the chilled cheesecake. Add fresh or frozen strawberries.
Garnish with mint or rosemary if you like. Use a warm knife to slice cleanly.
