Tips for the Perfect Crème Brûlée

To ensure that your Japanese Sweet Potato Crème Brûlée comes out perfectly, pay close attention to the baking time and water bath method. Baking in a water bath helps regulate the temperature, allowing for even cooking and a smooth custard texture. You can also monitor the custards for doneness by gently shaking them; they should be slightly set but still have a slight jiggle in the center.

When caramelizing the sugar, take your time with the kitchen torch. Move the flame back and forth evenly across the surface to achieve a uniform golden brown crust. If you don’t have a torch, you can also place the ramekins under the broiler. This dessert is best served fresh, so caramelize the sugar just before serving for the ultimate experience.

Ingredients

For the Crème Brûlée

2 medium Japanese sweet potatoes
2 cups heavy cream
4 egg yolks
1/2 cup granulated sugar
1 teaspoon vanilla extract
Pinch of salt
Additional sugar for caramelizing

Ensure all ingredients are at room temperature before starting.

Instructions

Prepare the Sweet Potatoes

Preheat your oven to 400°F (200°C). Poke holes in the sweet potatoes and bake them for about 30-40 minutes or until tender.

Make the Custard Mixture

Slowly whisk in the hot cream into the egg mixture to temper it, then stir in the mashed sweet potatoes.

Bake the Crème Brûlée

Pour the custard mixture into ramekins. Place the ramekins in a baking dish and add hot water to the dish until it reaches halfway up the sides of the ramekins. Bake for 30-35 minutes or until set.

Caramelize the Sugar

Let the custards cool, then refrigerate for at least two hours. Before serving, sprinkle a thin layer of sugar over the top and use a kitchen torch to caramelize the sugar until golden and crispy.

Serve immediately after caramelizing the sugar for the best texture.

Storage and Meal Prep

If you’re planning to make Japanese Sweet Potato Crème Brûlée in advance, you can prepare the custards ahead of time. Store them in the refrigerator for up to 24 hours before caramelizing the sugar. However, it’s important to wait to caramelize until you're ready to serve, as the texture of the sugar topping is best when fresh and crispy.

For extra convenience, you may double the recipe and enjoy leftovers the next day, although the sugar topping will need to be re-caramelized for optimal crunch. Although this dessert is rich, it can easily be portioned into smaller servings, allowing for a delightful treat without indulgence.

Finding the Perfect Sweet Potatoes

Selecting the right Japanese sweet potatoes is key to achieving the best flavor in your crème brûlée. Look for firm potatoes with smooth skin and a vibrant purple hue. These varieties typically have a sweeter and creamier consistency when baked, which will elevate the custard's taste.

If you can access organic sweet potatoes, they are generally recommended to ensure you get the purest flavor without unwanted chemicals. Keep in mind that not all sweet potatoes are created equal; the Japanese variety, recognized for its unique sweetness, is the star of this recipe.
