Step-by-Step Instructions
How to Make Japanese Sweet Potato Crème Brûlée
Preheat your oven to 400°F (200°C). This will get things ready for roasting our sweet potatoes, which is the first task for this tasty dessert.
Roast sweet potatoes for about 45 minutes or until tender. You’ll know they’re ready when you can easily pierce them with a fork. Let them cool slightly, this is super important before you scoop out the flesh!
Scoop the flesh into a bowl. This is where the magic begins! With a fork, mash the sweet potato until smooth. Make sure there are no lumps because we’re going for creamy perfection here! Seriously, the fluffier the better!
In a saucepan, heat the heavy cream until it’s just about to simmer. Keep an eye on it and stir occasionally. We want it hot, but not boiling. Yum, that smell!
In a separate bowl, whisk together the egg yolks, sugar, vanilla extract, and salt until smooth. You’ll want to keep whisking until it’s all well combined and looks luxurious.
Slowly add the warm cream to the egg mixture while continuously whisking. This is the tempering process. You don’t want to scramble the eggs! So, go slow and enjoy the moment… it smells divine.
Fold in the roasted sweet potato flesh until combined. This is where it all comes together, just gently fold it in until no streaks remain.
Pour the mixture into ramekins and place them in a baking dish filled with water (water bath). This keeps everything moist while baking and helps with that creamy texture.
Bake in the oven for about 30-35 minutes or until set. They should be slightly wobbly in the center, quite like a perfect custard.
Cool and refrigerate for at least 4 hours or overnight. Patience is key! This helps the flavors meld together beautifully. Plus, it’s a great make-ahead dessert.
Before serving, sprinkle sugar on top, then use a torch or broiler to caramelize the sugar until golden and crispy. The sound of crackling sugar is like music to my ears! Just watch it carefully; burnt sugar is… well, sad.
