Helpful Tips for Success

Ingredients

For the Custard

  • 2 medium Japanese sweet potatoes
  • 1 cup heavy cream
  • 1/2 cup milk
  • 1/2 cup granulated sugar
  • 4 large egg yolks
  • 1 teaspoon vanilla extract
  • Pinch of salt

For the Caramel Top

  • Extra granulated sugar for caramelizing

Ensure all ingredients are prepared before starting the recipe.

Instructions

Prepare the Sweet Potatoes

Begin by peeling the Japanese sweet potatoes and cutting them into chunks. Steam or boil them until they are soft, about 15 to 20 minutes.

Make the Custard

In a mixing bowl, combine the cooked sweet potatoes, heavy cream, milk, sugar, egg yolks, vanilla extract, and salt. Blend the mixture until smooth and creamy.

Bake the Custard

Preheat your oven to 325°F (160°C). Pour the custard mixture into ramekins and place them in a baking dish. Fill the baking dish with hot water until it reaches halfway up the sides of the ramekins.

Bake for about 30-40 minutes or until set.

Chill

Remove the ramekins from the water bath and let them cool at room temperature. Once cooled, refrigerate for at least 2 hours.

Caramelize the Sugar

Sprinkle a thin layer of granulated sugar on top of each chilled custard. Use a kitchen torch to caramelize the sugar until it is golden and bubbly. Allow it to cool for a few minutes before serving.

Serve immediately after caramelizing the tops for the best texture.

Storage Tips

Japanese Sweet Potato Crème Brûlée can be prepared in advance, making it an excellent option for busy hosts. Once baked and chilled, the custards can be stored in the refrigerator for up to three days. Simply add the caramelized sugar topping just before serving to ensure it remains crispy and delightful.

For longer storage, be sure to keep the caramel layer separate from the custard. Avoid trying to freeze the custards, as the texture may suffer upon thawing. Instead, focus on enjoying them fresh for the best experience!

Serving Suggestions

Pair your Japanese Sweet Potato Crème Brûlée with a dollop of whipped cream or a scoop of vanilla ice cream for added indulgence. Fresh berries, such as raspberries or blueberries, can add a refreshing tartness that complements the rich sweetness of the dessert beautifully.

For an extra touch, consider pairing the dessert with a cup of green tea. The mild bitterness of the tea can balance the sweetness of the crème brûlée, enhancing the overall tasting experience. This thoughtful pairing reflects the dish's Japanese roots, creating a cohesive dining experience.
