Silky custard meets sweet Japanese potato in this caramelized French-Japanese fusion dessert.
# What You'll Need:
→ Sweet Potato Custard
01 - 1 large Japanese sweet potato (approximately 9 ounces), peeled and cut into 1/2-inch cubes
02 - 1 cup heavy cream
03 - 1/2 cup whole milk
04 - 4 large egg yolks
05 - 1/4 cup granulated sugar

07 - Pinch of salt
→ For the Caramelized Top
08 - 3 to 4 tablespoons granulated sugar for brûlée topping
# How-To Steps:
01 - Preheat oven to 300°F. Fill a kettle with water and bring to a boil for the water bath.
02 - Steam or boil sweet potato cubes until completely tender, approximately 15 minutes. Drain thoroughly and allow to cool slightly.
03 - Combine cooked sweet potato, heavy cream, and milk in a blender or food processor. Blend until completely smooth and no lumps remain.
04 - Whisk egg yolks, granulated sugar, vanilla extract, and salt in a mixing bowl until pale yellow and smooth.
05 - Slowly pour sweet potato cream mixture into egg yolk mixture while whisking continuously to prevent curdling.
06 - Pour combined mixture through a fine mesh sieve into a clean bowl to remove any remaining lumps and ensure silky texture.
07 - Divide custard evenly among 4 ramekins. Place ramekins in a deep baking pan.
08 - Carefully pour boiling water into the baking pan until it reaches halfway up the sides of the ramekins.
09 - Transfer pan to oven and bake for 30 to 35 minutes, until custard is set but still slightly wobbly in the center.
10 - Remove ramekins from water bath. Let cool to room temperature, then refrigerate for at least 2 hours or until completely chilled.
11 - Sprinkle 1 tablespoon sugar evenly over each chilled custard. Use kitchen torch to caramelize until golden brown and crispy, or broil briefly under oven grill watching constantly.
12 - Let brûlée rest for 3 minutes before serving to allow caramelized sugar to harden completely.
