This is an ultra-smooth and creamy ice cream, with the fresh, slightly earthy flavor that makes matcha so unique. More refreshing than it is sweet, matcha ice cream tastes like a creamy scoop of iced green tea.
Place the matcha powder in a saucepan and whisk to remove any lumps. Add a splash of milk and whisk again until the powder is completely dissolved. Gradually whisk in the remaining milk. Gradually whisk in the cream.
Add the sugar and whisk to combine. Cook over medium-low heat, stirring occasionally, until heated through, about 5 minutes.
Remove from the heat and cool to room temperature, about 20 minutes. Refrigerate until chilled, at least 2 hours.
Pour the cold mixture into an ice cream maker and process according to the manufacturer's instructions. Serve immediately or transfer to an airtight container and freeze until ready to serve.
