'- 500 ml high quality vanilla ice cream of your choice- 1 tablespoon matcha (green tea) powder- 1 tablespoon lukewarm, slightly hot, drinking water

1. Place the ice cream in the fridge for 15 to 30 minutes to soften it slightly. Don't let the ice cream melt.2. Mix together matcha powder and warm water in a small cup and stir well to make a smooth paste.3. Transfer half of the ice cream to a mixing bowl, and mix with matcha paste with a spatula until thoroughly mixed, then add the rest of the ice cream. If you want a marble effect, stop mixing when the ice cream looks like a marbled green and white. If you want a uniform green color, continue mixing until the ice cream is uniformly green.4. Place the bowl into a freezer. Once the ice cream has hardened again, it is ready to serve, about 1 hour.
