Bring milk to a boil. Remove from heat and add green tea. Mix well. In a separate bowl, beat egg yolks and sugar until they form a ribbon. Combine egg mixture with 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-and-half over ice water until frothy. Pour into egg mixture and mix well. Process in ice cream maker according to manufacturer's directions. Freeze 2-3 hours before serving. From Della Masia, Prodigy Id# Txbg93a. Mm:Mk VMXV03A.
