1-1/2 ounces unsweetened cocoa powder, approximately 1/2 cup
3 cups half-and-half
1 cup heavy cream
8 large egg yolks
1-1/4 cups sugar
2 teaspoons pure vanilla extract
Place the cocoa powder along with 1 cup of the half-and-half into a medium saucepan over medium heat and whisk to combine. Add the remaining half-and-half and the heavy cream. Bring the mixture just to a simmer, stirring occasionally, and remove from the heat.
In a medium mixing bowl whisk the egg yolks until they lighten in color. Gradually add the sugar and whisk to combine.
Temper the cream mixture into the eggs and sugar by gradually adding small amounts, until about 1/3 of the cream mixture has been added. Pour in the remainder and return the entire mixture to the saucepan and place over low heat. Continue to cook for a few minutes, stirring frequently, until the mixture thickens slightly and coats the back of a spoon.
Pour the mixture into a container and allow to sit at room temperature for 30 minutes. Stir in the vanilla extract. Place plastic wrap on top to prevent a film from forming. Then place the mixture into the refrigerator and let cool for 4 to 24 hours.
Pour into an ice cream maker and process according to the manufacturer’s directions.
Variation: use only 7 egg yolks. Use 2-1/2 c. heavy cream and 1-1/2 c. International Delight Vanilla Coffee Creamer. Decrease sugar to 1/2 c. Eliminate vanilla.
