01 - Combine milk and cream in a medium saucepan. Heat over medium heat until steaming but not boiling.
02 - Add hojicha tea to the hot dairy mixture. Remove from heat and let steep for 10 minutes to infuse the roasted, nutty flavor.
03 - Strain the mixture through a fine sieve, pressing firmly on the tea leaves to extract maximum flavor. Discard the tea leaves and return the infused milk-cream mixture to the saucepan.
04 - In a separate mixing bowl, whisk together egg yolks, sugar, and salt until the mixture becomes pale and creamy in texture.
05 - Gradually pour the warm hojicha-infused dairy mixture into the egg yolks while whisking constantly. This tempering process prevents the eggs from curdling.
06 - Return the mixture to the saucepan. Cook over low heat, stirring constantly with a wooden spoon, until the custard thickens and coats the back of the spoon, approximately 6-8 minutes. Do not allow the mixture to boil.
07 - Pour the custard through a fine sieve into a clean bowl. Allow it to cool to room temperature, then cover and refrigerate for at least 3 hours or until thoroughly chilled.
08 - Churn the chilled custard in an ice cream maker according to the manufacturer's instructions until it reaches a soft-serve consistency.
09 - Transfer the churned ice cream to an airtight container. Cover and freeze for at least 1 hour before serving to allow it to firm up properly.
