Black Sesame Oolong Tiramisu

1: Start by mixing sugar and egg yolks in a small bowl. Cook this mixture on a double boiler while whisking it continuously for 10 minutes. Once done, remove it from heat and let it cool slightly.

2: In a large bowl, use a hand mixer to whip the cream until it forms soft peaks. Add vanilla extract and continue whipping until it forms firm peaks.

3: In another separate bowl, whisk together mascarpone and sesame paste. Add the yolk mixture to it and whisk until combined. Then, add half of the whipped cream and whisk again. Finally, fold in the remaining half of the whipped cream.

4: Dip the ladyfingers in oolong tea for 1 second and then place them in a 9x9 pan. Layer the first 14 ladyfingers in the pan and then spread half of the sesame mascarpone mixture on top. Repeat this process once more.

5: Cover the tiramisu with plastic wrap and refrigerate it overnight.

6: Before serving, dust cocoa powder over the top.
