Ingredients
355gheavy cream 1½ cups
245gwhole milk 1 cup
135ggranulated sugar ⅔ cup
4large egg yolks
40gJapanese whisky 3 tbsp
11gceremonial-grade matcha 1½ tbsp
4.5gvanilla extract 1 tsp
1.5gfine salt ¼ tsp
Instructions
Confirm bowl frozen 24+ hours. Sift matcha. Whisk with 2 tbsp cold milk until smooth paste.
Heat remaining cream, milk, and salt until steaming.
Whisk yolks and sugar. Temper in two additions. Cook to 170–175°F.
Remove from heat. Whisk in matcha paste until smooth. Stir in whisky and vanilla.
Frozen bowl: 24+ hours. 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.
