Serves: 4-6 servings
2 egg yolks
3/4 cup granulated sugar
3 cups Guinnes Draft, about 1 1/2 cans
1/2 cup milk
1 cup whipping (35%) cream
1. In a bowl, whisk egg yolks with sugar until thickened and pale yellow. Set aside.
2. In a medium saucepan over medium heat, cook Guinness, stirring occasionally, until reduced by half. Reduce heat to low. Stir in milk. Bring to a simmer. Gradually whisk into the egg mixture.
3. Return entire mixture to the saucepan. Cook over low heat, stirring constantly, until the mixture is thick enough to coat the back of a wooden spoon. Be careful not to let it boil. Strain into a clean large bowl. Let cool to room temperature.
4. Stir in cream. Cover and refrigerate until completely cold or overnight.
5. Stir cream mixture. Transfer to an ice cream maker and freeze according to manufacturer's instructions.
