Black Sesame Cottony Cheesecake - cooking recipe

Ingredients

8 ounces cream cheese
3 1/2 tablespoons unsalted butter
100 ml cream (35% milk fat)
60 g cake flour
1/4 cup cornflour
6 egg yolks
1 tablespoon lemon juice
1/4 teaspoon salt
1 tablespoon black sesame powder
6 egg whites
1/4 teaspoon cream of tartar
140 g caster sugar
2 tablespoons milk

Preparation

Melt cream cheese and butter over a double boiler. Whisk to combine. Set aside to cool. Add the cream and whisk to combine.
Meanwhile, line and grease the base and side of a 8-inch spring form cake pan. Preheat oven to 160C (fan-forced).
Sift the cake flour and corn flour to the cheese mixture. Add in egg yolk, lemon juice, sesame powder and salt. Gently whisk to thoroughly combine all the ingredients. At this stage, if your mixture is a bit too stiff, add in 1-2 tbsp of milk. The mixture should be similar to your normal cake mixture.
Whisk egg white with cream of tartar until foamy. Add sugar, tablespoon by tablespoon. Whisk until soft peak forms (don't whip the egg white too stiff, the cake will be likely to crack).
Add 1/3 of the egg white to the cheese mixture to lighten it. Then, gently but thoroughly fold the egg white to the cheese mixture. Be careful not to destroy all the air bubbles in the egg white.
Gently pour into the prepared pan. Using foil, wrap the outside of the pan. Put the cake pan into a roasting pan. Add boiling water to half-way of the cake pan.
Bake in the oven for 1 hour 10 min or until the cake is set.
Take out, leave in the pan to cool. Serve at room temperature.
