Makes about 2 cups
Ingredients
  • 1½ cups (360 grams) water
  • 1¼ cups (250 grams) plus ⅓ cup (67 grams) granulated sugar, divided
  • ¾ cup plus 2 tablespoons (228 grams) roasted and peeled chestnuts
  • 1⅓ cups (320 grams) heavy whipping cream
  • 1¼ teaspoons (5 grams) unflavored gelatin
  • 3 large eggs (150 grams)
  • 5 large egg yolks (93 grams)
  • 2 tablespoons (28 grams) unsalted butter
Instructions
  1. In a large saucepan, bring 1½ cups (360 grams) water, 1¼ cups (250 grams) sugar, and chestnuts to a boil over medium-high heat. Reduce heat to low, and simmer for 30 minutes. Strain chestnut mixture into a large bowl, reserving ⅓ cup (113 grams) chestnut syrup. Let cool completely.
  2. Transfer candied chestnut mixture to the work bowl of food processor; process until finely chopped. Set aside.

  4. In a medium bowl, whisk together eggs, egg yolks, and remaining ⅓ cup (67 grams) sugar. Slowly pour hot cream mixture into egg mixture. Return cream mixture to saucepan, and cook, whisking constantly, until mixture registers 180°F (82°C) on a candy thermometer. Remove from heat, and stir in butter. Strain into a medium bowl. Stir ¾ cup candied chestnut purée into cream mixture. Use immediately.
