04 - Whisk egg yolks, sugar, and salt in a separate bowl until pale and creamy in texture.
05 - Gradually pour warm hojicha mixture into yolks while whisking constantly to prevent curdling.

07 - Pour custard through a fine sieve into a clean bowl. Cool to room temperature, cover, and refrigerate for at least 3 hours until thoroughly chilled.
08 - Churn in an ice cream maker according to manufacturer's instructions until frozen to soft-serve consistency.
