You can never be too rich or eat too much chocolate and peanut butter.
2 cups heavy cream
1/2 cup whole milk
6 oz good quality dark semi-sweet chocolate, chopped
5 egg yolks
1/2 cup sugar
Place cream, milk and chocolate into medium pot. Heat, stirring, until the chocolate is melted and the mixture just starts to simmer.
Beat egg yolks and sugar in a bowl until pale and thick. Once cream mixture is hot slowly whisk half of the cream mixture into the egg mixture (as to not cook the egg), then pour back into the pot.
Return mixture back to low heat, stirring constantly with wooden spoon until mixture coats the back of spoon.
Pour mixture into a bowl, cover, and refrigerate until fully cooled.
Once chilled, pour into ice cream maker and set machine on ice cream. I use a Breville ice cream maker and I love it.
