# How to Make It:

01 - Preheat your oven to 300°F. Place a kettle of water on to boil for the water bath.
02 - Steam or boil the sweet potato cubes until very tender, about 15 minutes. Drain and let cool slightly.
03 - In a blender or food processor, blend the sweet potato with heavy cream and milk until completely smooth.
04 - In a mixing bowl, whisk together egg yolks, sugar, vanilla, and salt until pale and smooth.
05 - Slowly pour the sweet potato mixture into the egg yolk mixture, whisking continuously.
06 - Strain the mixture through a fine mesh sieve into a clean bowl to ensure a smooth custard.
07 - Divide custard evenly among 4 ramekins and place them in a deep baking pan.
08 - Pour hot water into the pan to reach halfway up the sides of the ramekins.
09 - Carefully transfer to the oven and bake for 30–35 minutes, or until the custard is just set but still slightly wobbly in the center.
10 - Remove ramekins from the water bath and let cool to room temperature, then refrigerate for at least 2 hours or until chilled.
11 - Just before serving, sprinkle 1 tablespoon of sugar over each custard. Use a kitchen torch to caramelize the sugar until golden and crisp (or briefly broil under the oven grill, watching closely).
12 - Allow the brûlée to rest for 3 minutes before serving, so the caramel hardens.

# Expert Suggestions:

01 -
  • The earthy sweetness of Japanese sweet potato transforms crème brûlée into something completely new yet comfortingly familiar
  • That crackle of burnt sugar gives way to the most surprisingly creamy custard youve ever tasted
02 -
  • Overbaking is the enemy of silky custard, so pull them out when they still have a slight wobble in the center
  • The water bath must reach exactly halfway up the ramekins or the custard will cook unevenly
03 -
  • Room temperature eggs incorporate more smoothly into the custard base
  • If you do not have a kitchen torch, use your oven broiler but watch it like a hawk since sugar goes from perfect to burnt in seconds
