# What You Need:
→ Sweet Potato Custard
01 - 1 large Japanese sweet potato (about 9 ounces), peeled and cubed
02 - 1 cup heavy cream
03 - 1/2 cup whole milk
04 - 4 large egg yolks
05 - 1/4 cup granulated sugar
06 - 1/4 teaspoon vanilla extract
07 - Pinch of salt
→ For the Caramelized Top
08 - 3–4 tablespoons granulated sugar (for brûlée)
# Directions:
01 - Preheat oven to 300°F. Bring a kettle of water to boil for the water bath.
02 - Steam or boil sweet potato cubes until very tender, approximately 15 minutes. Drain and allow to cool slightly.
03 - Blend sweet potato with heavy cream and whole milk in blender or food processor until completely smooth.
04 - Whisk together egg yolks, granulated sugar, vanilla extract, and salt in mixing bowl until pale and smooth.
05 - Slowly pour sweet potato mixture into egg yolk mixture while whisking continuously to prevent curdling.
06 - Pour mixture through fine mesh sieve into clean bowl to ensure perfectly smooth custard texture.
07 - Divide custard evenly among 4 ramekins and place in deep baking pan.
08 - Pour hot water into baking pan until it reaches halfway up sides of ramekins.
09 - Carefully transfer to oven and bake for 30–35 minutes until custard is just set but still slightly wobbly in center.
10 - Remove ramekins from water bath and cool to room temperature. Refrigerate at least 2 hours or until thoroughly chilled.
11 - Sprinkle 1 tablespoon sugar over each custard. Use kitchen torch to caramelize until golden and crisp, or broil briefly under oven grill watching closely.
12 - Allow brûlée to rest 3 minutes before serving so caramel fully hardens.
