5largeegg yolks
40gJapanese whisky 3 tbsp
15gceremonial-grade matcha 2 tbsp
4.5gvanilla extract 1 tsp
1.5gfine salt ¼ tsp
Instructions
Sift matcha. Whisk with 2 tbsp cold milk until smooth paste forms.
Heat remaining cream, milk, and salt until steaming.
Whisk yolks and sugar until pale. Temper in two additions.
Cook to 170–175°F. Remove from heat. Whisk in matcha paste until fully green and smooth.
Stir in whisky and vanilla. Strain and chill 4 hours or overnight.
Churn 20–25 minutes. Freeze 4 hours until firm.
Notes
Use ceremonial-grade matcha — culinary grade tastes bitter and chalky when cold. Sift the matcha and make the paste before you start the custard. Matcha clumps are nearly impossible to remove once they’re in the base, and straining won’t catch fine grit.
