Start by preheating your oven to 375°F and preparing a 9-inch springform pan by greasing it thoroughly and lining the base with parchment paper.
In a large mixing bowl, beat ⅔ cup (150g) of softened salted butter together with 1 cup + 6 tbsps (275g) of granulated sugar and 2⅓ cups (550g) of full-fat cottage cheese or ricotta until the mixture becomes creamy and well combined.
Add the 4 extra-large egg yolks one at a time, beating well after each addition to guarantee they're fully incorporated. Then fold in the 1¼ cups (115g) of almond flour, ¾ cup (115g) of golden raisins, ⅓ cup (55g) of semolina, and the finely grated zest and juice of 2 lemons.
Allow this mixture to rest for 10 minutes to let the flavors meld and the dry ingredients fully hydrate.
While the batter rests, whisk the 4 egg whites until they form stiff peaks. Gently fold the whipped egg whites into the lemon mixture in batches, being careful not to deflate them—this whipped egg white is what gives the cheesecake its characteristically light and fluffy texture. Pour the batter into the prepared springform pan and transfer it to the preheated oven.
Bake for approximately 1 hour, covering the top with foil halfway through the baking time to prevent the surface from over-browning.
Once baked, turn off the oven and crack the door slightly open, allowing the cheesecake to cool inside for 1 hour. This gradual cooling process prevents the cheesecake from cracking or sinking. Remove the cheesecake from the oven and allow it to cool completely at room temperature.
Once fully cooled, loosen the edges with a knife, release the springform pan, carefully invert the cheesecake to peel off the parchment paper, and turn it upright once more. Finish by dusting the top generously with confectioners' sugar just before serving.
