Green Tea Ice Cream

In a saucepan, heat milk slowly to boiling. Then add green tea leaves and cover. Let steep (simmer) for about 15 minutes. Meanwhile, in a mixing bowl, beat egg yolks with sugar and cornstarch. Remove milk from heat and strain out the tea leaves. Whisk in egg mixture, whisking constantly to keep the eggs from cooking in the hot milk. When mixture is starting to thicken, transfer to a larger bowl and allow to cool. Then stir in the heavy cream. Freeze mixture for at least 2 hours before serving.
