ABOUT THIS RECIPECreamy, toasted and fresh
Tahini gives this cheesecake a distinct toasted flavor and a hint of bitterness without overpowering the creamy base. Use smooth tahini and stir the jar well first, so the oil and sesame paste come together again. The flavor varies by brand: taste the tahini before you start, and if it’s particularly strong, consider using 75 grams instead of 90. A little salt in the filling keeps the sweetness in balance.
A cookie crust is practical for a compact cake and doesn’t need to be complicated. Finely ground biscuits make a firm, even layer; press the crumb mixture down with the bottom of a glass, especially around the edges. Briefly pre-baking the crust makes it less crumbly when you slice the cheesecake. An 18-centimeter springform pan gives you a tall cake. If you use a 20-centimeter pan, the cheesecake will be a little lower and may need a few minutes less baking time.
Cream cheese, eggs and sour cream mix most smoothly when they aren’t ice-cold. Mix the filling gently and stop as soon as there are no more lumps: too much air in the batter can make it expand while baking and then sink again. The cheesecake is ready when the edge looks firm and the center still wobbles slightly when you gently move the pan. Letting it cool slowly, first in the switched-off oven and then on the counter, limits large temperature changes. A small crack is no problem; the orange and crunchy sesame give the top its own finish anyway.
Oranges are generally widely available, with plenty to choose from in the colder months. Zest the peel before peeling the fruit, then cut the segments out between the membranes, or peel the orange and cut it into neat pieces. Mandarin segments work too, but they’re smaller and often sweeter. The citrus makes every bite fresher and cuts through the rich mouthfeel of the cream cheese and tahini.
Make the sesame brittle with sugar and sesame seeds; let the caramel turn light amber for a toasted note, but take the pan off the heat before it gets dark. Spread it thinly and break it only once it has cooled completely. Moisture makes caramel sticky, so store the brittle separately in a well-sealed, dry container and put it on the cake just before serving. Keep the cheesecake covered in the fridge and eat it within three days. Serve small slices after a hearty meal, or with coffee or black tea.
