For soaking syrup and oranges:
- 2 bay leaves
- 1/3 cup granulated sugar
- Pinch of kosher salt
- 1/2 cup water
- 2 – 3 teaspoons fresh lemon juice, divided
For the cake:
- Butter for pan
- ¾ cup (6 oz) Kalona SuperNatural Whole Milk, divided
- Large pinch saffron threads, crushed
- ¾ cup (1½ sticks)
- Kalona SuperNatural Unsalted Butter 1 cup (7 oz/200 g) granulated sugar
- zest from 3 medium organic oranges
- 1½ cups (9 oz/255 g) coarse-grind semolina flour (such as Bob’s Red Mill)
- 2 teaspoons (1/4 oz/5 g) baking powder
- 1 teaspoon ground cardamom
- 1/2 teaspoon kosher salt
- 1 cup (8 oz/230 g) Kalona SuperNatural Plain Whole-Milk Greek Yogurt
For the filling:
In a small saucepan add bay leaves, sugar, salt, and ½ cup water. Bring to a simmer and stir occasionally to dissolve sugar, about 5 minutes. Remove from heat and stir in 2 teaspoons lemon juice. Set aside to cool.
Preheat oven to 350°F. Butter the bottom and sides of a 9″- diameter cake pan, line the bottom with a round of parchment paper and butter paper. Set aside.
In a small saucepan warm 1/4 cup milk, add crushed saffron threads and stir until dissolved. Add butter to milk mixture and heat until butter is melted. Set aside to cool slightly.
In a medium bowl measure out sugar, add the orange zest and using your fingers evenly incorporate the zest into the sugar. Then whisk the semolina, baking powder, cardamom, and salt into the sugar.
In a large bowl whisk together yogurt and remaining milk. Using a spatula or wooden spoon mix the dry ingredients into the yogurt mixture. Stir in the cooled (still liquid) butter mixture and then scrape batter into prepared pan.
Bake cake until golden brown and firm to the touch, 50–60 minutes. It is done when a cake tester comes out clean. Transfer pan to a wire rack and allow cake cool in pan 10 minutes. Turn a 10″ rimmed plate or platter over top of pan and invert cake. Using a cake tester or toothpick, poke holes all over cake.
Reserve 1/4 cup of the bay leaf syrup in a medium bowl. Gradually pour remaining syrup over cake allowing it to soak in. Let sit at least 30 minutes.
Meanwhile, remove the remaining peel and white pith from oranges. Slice into ¼”-thick rounds; remove seeds and add to reserved bay leaf syrup. Gently toss the oranges on occasion and allow to macerate at least 30 minutes. Taste and add lemon juice as needed.
Whisk the mascarpone and heavy cream until soft peaks form. Whisk in vanilla extract.
Split cake horizontally. Using the bottom of a removable tart pan as a spatula carefully lift off the top half of the cake and set aside. Spread the mascarpone evenly over the bottom cake layer. Top with a layer of lemon curd-get recipe! Set the reserved layer on top of the filling. Sprinkle with powdered sugar.
