JAPANESE COTTON CHEESECAKE

Steps:

• Preheat the oven to 320 degrees F (160 degrees C). Grease an 8-inch round pan with butter and line the bottom with parchment paper.
• Fill a pot about 1/4 full with water and bring to a boil. Combine and milk in a heatproof bowl large enough to sit on top of the pot without touching the water. Reduce heat to medium and whisk until butter is melted, about 1 minute. Add cream cheese and whisk until smooth, about 2 minutes. Add honey and whisk until melted, about 1 minute. Remove bowl from heat.
• Add egg yolks, 1 at a time, to the cream cheese mixture; whisk batter well after each addition. Add lemon juice and zest.
• Use a fine mesh strainer to sift flour, cornstarch, and salt into the batter. Whisk until blended together. Pour batter through the strainer into a clean bowl to remove any lumps. Set aside.
• Whisk egg whites in a bowl until foamy. Add cream of tartar. Whisking continuously, slowly adding white sugar, until soft peaks form. Fold 1/3 the egg whites into the batter using a whisk. Fold in remaining egg whites. Pour batter into the prepared pan and tap on a flat surface to remove any air bubbles.
• Place a clean towel in the bottom of a shallow baking sheet. Place filled cake pan on top of the towel. Pour enough water into the baking sheet to come 1 to 2 inches up the side of the cake pan.
• Place baking sheet on the lowest rack of the preheated oven; bake for 20 to 22 minutes. Reduce temperature to 275 degrees F (135 degrees C), leaving oven door closed. Continue baking until mostly set but center is still jiggly, about 55 minutes more. Turn oven off and leave door ajar with cake inside for 30 minutes.
• Remove cake from pan. Decorate with confectioners' sugar and refrigerate for 1 to 2 hours before serving. Cake may also be served at room temperature.
