Mint Chocolate Chip Ice-Milk
In a small bowl stir about one-fourth milk mixture into yolks and pour into remaining milk mixture, whisking constantly. Cook mixture over low heat, stirring constantly, until slightly thickened and a thermometer registers 160 degrees. (Do not boil mixture or it will curdle.) Stir in creme de menthe and transfer mixture to a bowl. Chill mixture about 1 hour, or until cool.
