PEPPERMINT STICK ICE CREAM

Steps:

• In a medium saucepan, whisk together the egg yolks, sugar and salt until pale yellow. While whisking, slowly add the cream and the milk. Heat the mixture over medium-low heat, stirring constantly with a wooden spoon, until the mixture is thick enough to coat the back of the spoon or about 170 degrees on an instant-read thermometer, 10 to 12 minutes.
• Transfer the mixture through a fine-mesh sieve into a bowl to cool at room temperature. Stir in the peppermint extract. Cover and chill at least 4 hours or overnight. Set a 9-by-5-inch loaf pan in the freezer to chill.
• If adding the chocolate chunks, stir together the chocolate and vegetable oil and set aside. Churn the ice cream mixture in an ice cream machine according to manufacturer's instructions. During the last few minutes of processing, add the candy cane pieces and very slowly drizzle in the chocolate mixture. (If added too quickly, the chocolate will clump; when the ice cream has been fully churned, use a pair of kitchen shears to cut any pieces that are too large.) Transfer the ice cream to the prepared loaf pan, cover well with plastic wrap and freeze until firm.
