Ingredients

Scale
  • 7 medium Japanese sweet potatoes
  • ⅔ cup sugar
  • 3 egg yolks
  • ¼ cup cornstarch
  • ¼ tsp salt
  • 3 cups milk
  • 2 tbsp unsalted butter
  • 1 tsp vanilla extract
  • ¼ cup sugar for caramelizing

Instructions

  1. Preheat oven to 392°F (200°C). Wrap sweet potatoes in aluminum foil and roast for about 1 hour and 10 minutes until tender.
  2. While potatoes roast, prepare the custard: In a saucepan, combine sugar, cornstarch, and salt. Gradually whisk in milk over medium heat until thickened.
  3. In a bowl, lightly beat egg yolks. Slowly add about ¼ cup of hot milk mixture to yolks, then return to saucepan.
  4. Cook custard for another 2 minutes over medium heat, then remove from heat. Stir in butter and vanilla extract until smooth.
  5. Let custard cool at room temperature; cover with plastic wrap to prevent skin formation.
  6. After cooling, cut tops off sweet potatoes and scoop out one-third of the flesh. Fill each potato with custard cream.
  7. Sprinkle about 1 teaspoon sugar on top of each filled sweet potato. Use a blowtorch to caramelize until dark amber and bubbly. Allow to harden before serving.
