Step‑by‑Step Instructions for Japanese Sweet Potato Crème Brûlée

Step 1: Bake Sweet Potatoes
Preheat your oven to 355°F (180°C). Scrub the Japanese sweet potatoes clean and place them on a baking sheet. Bake for about 1 hour, or until the potatoes are tender when pierced with a fork. The skin will slightly wrinkle, indicating they’re ready for mashing.

Step 2: Mash Potatoes
Once the baked sweet potatoes are cool enough to handle, peel off the skin and place the flesh in a mixing bowl. Use a potato masher or fork to mash them until you achieve a completely smooth texture, ensuring a velvety consistency for your Japanese Sweet Potato Crème Brûlée.

Step 3: Combine Ingredients
In a large mixing bowl, combine the smooth sweet potato mash with the egg yolks, cornstarch, sugar, and heavy whipping cream. Whisk the mixture thoroughly until all ingredients are well blended. Look for a creamy, homogenous texture as this forms the base of your luscious custard.

Step 4: Cook Custard
Pour the mixture into a saucepan and cook it over medium heat, stirring constantly. Let it simmer gently for about 5-7 minutes, or until the custard thickens slightly and coats the back of a spoon. Take care not to let it boil, as you want to preserve that smooth texture.

Step 5: Chill Custard
Remove the custard from heat and allow it to cool at room temperature. Once cooled, pour the mixture into individual ramekins, filling them nearly full. Place the ramekins in the refrigerator for at least 2 hours to allow the custard to set completely and develop its flavors.

Step 6: Caramelize Sugar
After chilling, take the ramekins from the refrigerator. Sprinkle an even layer of granulated sugar over the top of each custard. Using a kitchen torch, gently caramelize the sugar until it melts and bubbles, creating a golden, crispy shell—about 30 seconds. Ensure the sugar is evenly browned for the best texture.

How to Store and Freeze Japanese Sweet Potato Crème Brûlée

Fridge: Store your Japanese Sweet Potato Crème Brûlée in an airtight container in the fridge for up to 2-3 days. Cover with plastic wrap to maintain moisture and prevent drying.

Freezer: While freezing is not recommended due to texture changes, if necessary, place wrapped ramekins in a freezer-safe bag for up to 1 month. Thaw in the refrigerator before serving.

Reheating: If caramelized sugar crust has softened, reheat briefly under the broiler for a few seconds to restore crunch. Ensure you monitor closely to avoid burning.

Make-ahead: Prepare the custard mixture up to 24 hours in advance, then store in the fridge before transferring to ramekins for a stress-free dessert.

Expert Tips for Japanese Sweet Potato Crème Brûlée

Smooth Mash: Ensure your sweet potatoes are completely smooth when mashing. Use a ricer or immersion blender for the creamiest custard texture in your Japanese Sweet Potato Crème Brûlée.
Heat Control: Cook the custard over medium heat only; too high can cause curdling. Stir continuously to maintain a velvety texture without burning the mixture.
Chill Long Enough: Allow the custard to chill for at least 2 hours before caramelizing. This resting time enhances firmness and flavor, ensuring a delightful serving experience.
Fine Sugar Matters: For the best caramel crust, always use fine granulated sugar. It melts more evenly, yielding a perfect golden-brown topping when torched.
Avoid Overcooking: When caramelizing the sugar, keep a close eye. Just a few seconds too long can turn your topping from beautifully crisp to burnt and bitter.
