Ingredients
For the Sweet Potato
- 7 medium Japanese Sweet Potato
For the Custard Cream
- ⅔ cup Sugar
- 3 Egg Yolk (omega 3)
- ¼ cup Cornstarch
- ¼ tsp Salt
- 3 cup Milk
- 2 tbsp Unsalted Butter
- 1 tsp Vanilla Extract
- ¼ cup Sugar
How to Make Japanese Sweet Potato Crème Brûlée
Step 1: Preheat the Oven
Preheat your oven to 392℉ (200℃). Wrap each sweet potato in aluminum foil and roast them for about 1 hour and 10 minutes until they are tender.
Step 2: Prepare the Custard Cream
While the sweet potatoes are roasting:
1. In a saucepan, mix together the sugar, cornstarch, and salt.
2. Gradually add in the milk while whisking to remove any lumps.
3. Heat this mixture over medium heat, continuously whisking until it thickens.
Step 3: Combine Egg Yolks with Milk Mixture
- In a small bowl, lightly beat the egg yolks.
- Slowly stir in about ¼ cup of the hot milk mixture into the egg yolks until well combined.
- Pour this egg mixture back into the saucepan with the remaining milk mixture.
Step 4: Finish the Custard Cream
Continue cooking over medium heat for another 2 minutes or until thickened. Remove from heat, then add in butter and vanilla extract. Whisk until everything is well combined.
Step 5: Cool the Custard Cream
Transfer your custard cream into a bowl. Cover it with plastic wrap, pressing it directly onto the surface to prevent skin formation. Let it cool at room temperature.
Step 6: Prepare Sweet Potatoes
Once roasted, allow the sweet potatoes to cool for about 10 minutes. Cut off their tops and scoop out about one-third of each potato’s flesh. Fill each potato cavity evenly with custard cream.
Step 7: Caramelize Sugar Topping
Sprinkle approximately 1 teaspoon of caster sugar evenly over each filled sweet potato. Using a blowtorch, carefully caramelize the sugar until it turns dark amber and bubbles up. Allow it to harden before serving.
