Whisk the Matcha Paste
5 Mins
Warm milk, ~40°C (104°F)
Warm 60ml of the milk until just warm to the touch, then whisk it into the sifted matcha a little at a time until you have a smooth, thick green paste with no lumps at all.
Sifting first is not optional — unsifted matcha clumps and will not dissolve in the custard.
Done when: A glossy green paste, smooth as paint, with no dry specks.

Warm the Cream and Milk
5 Mins
Medium heat, ~70°C (158°F)
Put the cream and the remaining 180ml of milk in a saucepan over medium heat and warm until steaming and small bubbles form at the edge — about 70°C (158°F). Do not let it boil.
Boiling scorches the milk and dulls the matcha colour, so pull the pan off the heat as soon as it steams.
Done when: Steaming, with tiny bubbles at the edge and no rolling boil.

Make the Custard
10 Mins
Low heat, up to 80°C (176°F)
Whisk the sugar into the yolks until pale. Pour the hot cream in slowly, whisking all the time, then return everything to the pan with the matcha paste, vanilla and salt. Cook over low heat, stirring constantly with a wooden spoon, until the custard coats the back of the spoon and reaches 80°C (176°F) — never above 82°C (180°F), or the yolks will scramble.
If the custard starts to thicken in streaks, lift the pan off the heat at once and keep stirring — it will even out.
Done when: A custard that coats the spoon and leaves a clean line when you draw a finger across it.

Chill the Base
25 Mins
Fridge, 4°C (40°F) or below
Pour the custard through a fine sieve into a clean bowl, press cling film directly onto the surface, and chill in the fridge until completely cold — at least 25 minutes in an ice bath, or 2 hours in the fridge.
The film stops a skin forming on the custard while it chills.
Done when: A cold, thick custard with no skin on top.

Churn the Ice Cream
25 Mins
Frozen bowl, -18°C (0°F)
Churn the cold base in an ice cream maker following the maker's instructions, usually 20–25 minutes, until it holds soft peaks. Without a maker, freeze the base in a shallow tray and beat it with a fork every 30 minutes for 3 hours to break up ice crystals.
A fully cold base churns in half the time and freezes smoother than a lukewarm one.
Done when: Soft-serve texture that holds its shape on a spoon.

Freeze Until Firm
240 Mins
Freezer, -18°C (0°F) or below
Spoon the churned ice cream into a freezer-safe container, press film onto the surface, seal, and freeze for at least 4 hours until firm enough to scoop.
Let the tub sit on the counter for 5 minutes before scooping — it cuts cleanly instead of shattering.
Done when: Firm, scoopable ice cream that keeps its shape in the bowl.
