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 extract maximum flavor.
03 - Strain the mixture through a fine sieve, pressing on tea leaves to extract all liquid. Discard tea leaves and return infused liquid to the saucepan.
04 - In a separate bowl, whisk egg yolks, sugar, and salt until pale and creamy in texture.
05 - Gradually pour the warm hojicha mixture into the yolks while whisking constantly to prevent curdling.
06 - Return mixture to saucepan and cook over low heat, stirring constantly with a wooden spoon until thickened and coating the back of the spoon, about 6-8 minutes. Do not allow to boil.
07 - Pour custard through a fine sieve into a clean bowl. Let cool to room temperature, then cover and refrigerate for at least 3 hours until thoroughly chilled.
08 - Churn the chilled custard in an ice cream maker according to manufacturer's instructions until reaching soft-serve consistency.
09 - Transfer churned ice cream to an airtight container, cover, and freeze for at least 1 hour before serving.
