Green Tea Ice Cream

Bring milk to a boil. Remove from heat and add green tea. Mix well. In a separate bowl, beat egg yolks and sugar together until they form a ribbon. Combine egg mixture and milk, then strain into a saucepan. Cook over medium-high heat until just before the mixture reaches a boil. Remove from heat and cool completely over ice water. Beat heavy cream and half & half until frothy. Pour into egg mixture and mix well. Process in an ice cream maker according to manufacturer's instructions.
